SSooffttwwaarreeSoftware Options

OMICRON users benefit from a wide range of powerful software options. Various packages contain a selection oftest modules that are function-oriented and can operate either on a stand-alone basis or can be embedded in testplans for automated testing. Additional software modules for special applications complete the range.

OMICRON´s software modules feature comprehensive functionality for conventional manualor automatic testing. Unique, however, are the automation possibilities the OMICRONControl Center offers. Comprehensive test plans can easily be built, maintained anddistributed; testing times can be significantly reduced.

OMICRON Control Center

With the OMICRON Control Center (OCC) technology all functions of a test object can be testedwith one test plan, defined within an OCC document.

Basically, an OCC document comprises the following elements:

Test object data Defined in XRIO, a powerful test object environment todescribe/model all test object parameters and settings. Testobject data can be entered manually or may be imported. XRIOConverters make the setting transfer from the relay to the testsoftware fast and easy.

Information on thedevice(s), outputs andinputs, wiring connections

Specified in Hardware Configuration Component (HCC). Presentthroughout a test plan for all embedded test functions/modules.

Test modules with testsettings (test points, etc.)

Number and type of embedded test modules depending on thecomplexity of the tests to be performed. With the LinkToXRIOtechnology, all "general" test modules have access to the XRIOparameters and allow the definition of test settings relative totest object parameters. Tests automatically adapt to changedtest object settings.

Optional: Graphics,instruction texts, etc.

Guides the tester through the testing process according to testspecifications (connection diagrams, check instructions, etc.)supported by Pause Module, Text View, ExeCute.

Results (after testing) Contains all test results in secure format with exact data,automatic assessment of the test points according to tolerances,automatically created test report (customizable to meet theorganization´s requirements).

To adapt a test plan for a certain parameter, only this single parameter needs to be changedin XRIO – all test settings adapt automatically, as they are set relative to the deviceparameters.

Re-usability

OCC documents can easily be used as templates for the same or similar tests: Simply copyingthe OCC file, deleting the results of the previous test and restarting will perform the testagain with the exact same settings, configuration, and test specifications. For similar tests,where only the parameterization differs (e.g. in substations with several feeders), simplecopying of the OCC file and adjustment of the parameters is all that is required.

Test Wizard, an efficient and customizable tool for the automatic generation of optimizedControl Center test plans, completes OMICRON´s “toolbox” for automatic testing and testplan creation.

Pause Module, Text View, ExeCute

These small modules run within OCC and support certain automation aspects.

Pause ModuleAllows the setting of breakpoints in automatic tests. Test designers can specify instructions to be displayed as pop up messages (e.g. inclusion of a wiring diagram).

Text ViewAllows for embedding and displaying a text file or log file during an automatic textexecution.

ExeCuteAllows for execution of external applications (programs) along with file or data parametersduring Control Center execution for an automatic test using an OCC document (e.g.automatic re-parameterization of a relay during type testing).

Hardware Configuration

In Hardware Configuration Component (HCC), the test setup (used generators/amplifiers,auxiliary CTs, VTs, etc.) and the wiring between the testing equipment and test object isconfigured with ultimate flexibility. Export and import functions allow easy distribution ofspecific hardware configurations.

SSooffttwwaarree

Test Object Definition with XRIO

All the relevant data for a device to be tested is kept in the standard XRIO format (eXtendedRelay Interface by OMICRON). The corresponding data can either be manually entered viaTest Object or alternatively it can be imported. Test object parameters can also be exported,making them available across any existing test plans.

LinkToXRIOAll test modules supporting LinkToXRIO allow the direct use of a defined test objectparameter for testing. This means that if a certain parameter changes, the test plans whichuse it do not need to be modified. The test plans will still perform their specified test usingthe now changed parameter.

XRIO ConvertersXRIO Converters optionally allow for the fast and easy entry and conversion of the dataavailable in the test objects´ own parameter structure. XRIO converters can be written andcustomized by the users. A number of helpful examples are included in the software.

Test LibraryA test library, installed with the software, additionally provides a comprehensive collection oftypical test object data of different manufacturers. The data can easily be adapted to theactual settings of individual test objects.




CM Engine - Programming Interface

For very special applications, the programming interface CM Engine - a command languagelibrary for 32-bit Windows platforms (Windows 98/2000/XP) - allows users of CMC test setsto write their own programs. Thus, specific test and control requirements can be met, suchas factory acceptance tests as performed by protection relay manufacturers.

The programs can be written in one of the common programming languages such asC/C++, Visual Basic or Pascal. It is also possible to control the CMC test hardware from third-party applications that support Microsoft Automation.

7

Automatic Reporting

All OMICRON test modules have one view in common - the report view. In this a fullyformatted report is available, missing only the test results. If several modules are used withinOCC to comprise a test, each module adds its specific piece of data to the overall report.

After testing is finished, test results and assessments are entered automatically to completethe report.

Reports can easily be printed, saved on file or in a database, or exported to standard officeapplications using Rich Text Format. Depending on the individual test module the resultscome from, data are entered in tabular and/or graphical form.

Customizing test reports based on individual requirements is easy. With the ReportConfiguration function the visible content of test reports can be defined completelyindependently from the recorded data, by just selecting or deselecting items from the list.Recorded data will always remain available regardless of whether the user chooses to includeit in the reports. Defined standard report settings are quickly and easily generated, saved,and loaded; company specific elements like logos etc., can easily be included.

Test Wizard

Test Wizard is a simple and efficient tool for the automatic generation of application tailoredtest plans in the OCC.

The basis of the Test Wizard is its “knowledge base“, a database of pre-defined individualtest plans for individual standardized test object types. This database can be customized andextended by the user.

Once the test object has been identified (e.g. a certain distance relay), Test Wizard providesa list of all protective functions available within this object (distance, autoreclosure, etc.).From this list, the user selects the functions to be tested and Test Wizard automatically putsthe corresponding testing functionality into a structured OCC document.

Like an assistant, Test Wizard guides the tester through the process of selecting the requiredtesting functions in an application-oriented way and automatically combines them for acomplete test plan in an OCC document.

The unique Test Wizard is of immense value in particular for use with multifunctional relays,representing also a powerful platform for the creation, distribution and maintenance ofstandardized test templates.

QuickCMC

Quick and easy manual testing• Simultaneous control of up to 16 generators (voltage/current outputs)• Steady state, step or ramp function for all quantities• Fault Calculator providing different operation modes• Timing measurements• Vector view and impedance plane

QuickCMC provides an easy and intuitive user interface, while also offering powerfulfunctions for performing manual tests for all kinds of secondary devices. Output quantitiescan either be entered in the classical way as voltages and currents, or by using input modesfor absolute or relative impedance values, powers or symmetrical components. Regardless ofwhich input mode is chosen, Fault Calculator transfers the values into voltages and currentsgenerated by a CMC and/or amplifier.

Output functions

QuickCMC provides simple control of test signals. Output values may be defined numerically,or by dynamically positioning the elements in the vector diagram, or the interactiveimpedance plane with the mouse.

The module includes a Fault Calculator which automatically converts the entered values todetermine the correct output quantities (voltage, current and phase angle) for single, two andthree-phase faults; power flow; or symmetrical components. The residual voltage and currentis also automatically calculated and generated. According to the selected mode, the values aredisplayed graphically in the vector or impedance view, as well as numerically in a table.

Channels where no fault model is assigned can be set without any restriction (unbalancedsignal generation, variable frequency for each individual channel, etc.).

The unit manager function allows for easy toggling between the handling of values inprimary/secondary, absolute/relative, or seconds/cycles.

Step or ramp mode

Step or Ramp Mode operation is provided for finding limiting values, such as pick up anddrop off, or starting of a relay. In step mode, the selected quantities (currents, voltages,impedances, power, etc.) are increased or decreased by a specified value with a mouse click.In ramp mode, a step function test is carried out until an input toggles or the user stops thetest. The pulse ramping functionality allows easy testing of protection elements withoverlapping characteristics.

Input/measuring functions

10 binary inputs can be used to monitor dry or wet contacts and make corresponding timemeasurements. The output values of a transducer connected to the analog dc inputs can alsobe displayed.

Reporting

Results of tests with QuickCMC can be stored for later use. Similar to all other testingmodules in the OMICRON Test Universe, the report style and content can be customized. Inaddition, the QuickCMC reporting feature provides a “notepad” function, so that individualcomments may be added to the report.

State Sequencer

State Sequencer is a very flexible tool for determining operating times and logical timingsequences. A state is defined by the output conditions (voltage and current, binary outputs)and a condition for the ending of the state. Several individual states can be strung togetherin order to define a test sequence. The transition from one state to the next may take placeafter a fixed time, after a trigger condition on the binary inputs of the CMC, a GPSsynchronization pulse, or by pressing a key. Static output of individual states is possible.

Definition of individual states

Within one state, up to 16 signals can be set independently in amplitude, phase, and frequency.Besides the direct input of the individual voltages and currents, the integrated fault calculatorallows the automatic calculation of the test quantities entered by one of the following inputmodes: Line-Neutral, Line-Line, symmetrical components, powers, fault values, Z with I or Vconstant. For distance relays, test points can directly be defined in the interactive impedanceplane, showing the specifications of the actual loaded XRIO test object file.

Measurement

Time measurements can be defined based on this string of states. These can be used to checkthe correct operation of the relay. Timing conditions can be specified for the test assessment(e. g., a given relay should trip within two cycles of inception of the fault state). Individual triptimes and deviations (positive and negative) can be specified for each measurement condition.If the measured time is within this range, the test is “passed”; otherwise, it is “failed”.Apart from timing measurements (always triggered by an event i.e. Trip) level assessmentscan be made. A level assessment is positive, if defined states at the relay outputs connectedto the binary inputs are logically true throughout a certain state. Changes of binary valuesare not required.

Once defined, states and timing conditions can easily be copied and pasted into sequence.

Assessment and Reporting

The measurement conditions are displayed in a table. After a test execution this table alsocontains the measured actual times and deviations. The last column contains the “passed”or “failed” information. All of the time signals (voltages, currents and binary inputs) can bedisplayed graphically to aid in studying the reaction of the relay. Signals can be enabledindividually, with the ability to zoom in on specific points in time. Data cursors facilitatescrolling through the time signals to find the values at specific times. The report functionalityis identical to all other automatic test modules.

State Sequencer supports the binary input/output unit CMB IO-7.

Pulse Ramping

With Pulse Ramping, quick, accurate and thorough determination of pickup values ofmultifunctional relays is easily done. Pulse Ramping allows for testing a protection elementpickup value without disabling associated functions. Trip is the only contact required. Thisremoves a potential source of error as no reparameterization of the relay is required. The useof Pulse Ramping also avoids high continuous testing current for electromechanical relayswith high instantaneous settings.

Other functions include:• Distance protection fault model with XRIO interface• Reset state definition• End-to-End testing using a GPS trigger• Automatic report creation• Automatic result assessment

Typical applications:Pick-up testing of• multifunctional relays with overlapping elements,• overcurrent relays with multiple elements,• generator protection,• motor protection,• rate of change relays (including df/dt).

Application Example Overcurrent:

Without Pulse Ramping, the I>> pickup (instantaneous) cannot be determined because theramp already leads to a trip in the I> (Timed Overcurrent) area.

With Pulse Ramping the determination of the I>> pickup value is easy because the 200mspulses never lead to a trip in the I> region.

Ramping

Ramping generates ramps of amplitude, phase, or frequency for the current and voltageoutputs. It can also determine limiting values, such as minimum pick-up or switching hysteresis.

Automated tests can be performed with ramps that allow testing of both simple andcomplex functions. The flexibility of this module allows two synchronized simultaneousramps of different variables and functions with up to five consecutive ramp segments each.

Features• Automated testing using ramp sequences• Simultaneous ramps for two independent variables and functions (e.g. V/Hz)• Definition of up to five consecutive ramp segments• Visual control of the output values (time view)• Display of the test results with automatic assessment• Test repetition feature with statistic calculations• Ratio calculations of the two ramp values, e.g. resetting ratio• Unique one-step-back feature for quick and accurate testing• Automatic result assessment

Typical Applications• Pick up/Drop-off testing• Evaluation of the resetting ratio



11

Autoreclosure

Configuration of the test sequences for the autoreclosure (AR) is both effective and timesaving. Autoreclosure automatically sets up test conditions for the successful andunsuccessful sequence. The user may modify the measurement conditions to special needs.Essential criteria, like the three phase final trip at the end of an unsuccessful sequence, areautomatically evaluated as well.

The generation of the fault quantities makes no assumptions for the nature of protection, soovercurrent, distance, or line differential relays with AR can be tested. The fault specificationis done by fault type and fault quantities, supported by the integrated fault calculator andthe LinkToXRIO functionality. For testing distance protection, the fault can be specified in theimpedance plane.

The test sequence is displayed over time and a list of events with assessments is reported.

Overcurrent

Automatic• Overcurrent trip time testing• Overcurrent curve evaluation• Pick-up/drop-off testing

Overcurrent serves to manually or automatically test overcurrent relays (directional and non-directional). The software displays the characteristic of the relay on a time vs. currentdiagram. Each test point is defined in this characteristic and then added to a test point list.An assessment is made for each test point, based on the pre-defined tolerance for the triptime.

Key Features• Assessment for each test point• Automated testing• Characteristic for zero and negative sequence• Definition of a test point sequence• Testing of the starting characteristic/automatic assessment• Testing with or without load current• Automatic reporting

Four different characteristics can be set for each relay: line to earth fault, line to line fault,zero sequence, and negative sequence.

The time characteristics or curves can either be based on a user-defined current vs. time tableor a variety of pre-defined relay characteristics. The relay characteristics available from theOMICRON templates are: standard inverse curves as defined by IEC 255-4 (BS 142) and relayspecific curves based on the IEEE standard formula (PC37.112).

OMICRON´s relay interface (XRIO) allows importing and exporting of relay data. Testautomation is supported by a simple test point definition in a user-defined test point list. Agraphical user interface displays the output values in the vector diagram.

Differential

Differential provides a compact testing solution for line, generator, busbar, and transformerdifferential protection relays. It performs single-phase tests of the operating characteristic(pick up value, slope test) and the inrush blocking function (harmonic restraint test).

Variable tap settings, as for some older electromechanical relays (e.g. GE BDD, orWestinghouse HU) can be addressed.

For the operating characteristic test, test points are defined in the Idiff/Ibias plane either bythe mouse or by using the keyboard. A graphic user interface makes the test definition easy.

Differential also tests the harmonic restraint function. For this function, the test points aredetermined by the differential current and the percentage of the superimposed harmonic.

The test currents belonging to the test points are injected into the relay and the reaction ofthe relay is assessed.

Distance

Distance provides the functionality to define and perform tests of distance relays byimpedance element evaluations using single-shot definitions in the Z-plane with graphicalcharacteristic display.

Definition of relay characteristics

A graphical characteristic editor makes for quick and easy definition of the nominal relaycharacteristics and settings. Starting, trip, extended, and no-trip zones can be defined byusing pre-defined elements. A complete overview of all defined zones is provided.

The standard XRIO interface makes it possible to directly import the relay data from the relaysparameter setting software. The impedance settings for the zones are entered and displayedin primary or secondary values, as chosen by the user.

Definition of tests

Tests are defined in the impedance plane: Test points are added to a test point table with themouse or by keyboard entry. This table is divided according to the different fault loops (A-N,B-N, C-N, A-B, etc.). Test points can be defined for several fault loops at the same time (e.g.for all single-phase loops), or for every fault loop separately.

When a test is performed, the test point lists belonging to the individual fault loops areprocessed in turn. The reaction of the relay is compared to the specified nominal settings andan assessment is made. The results are displayed graphically in the impedance plane, as wellas numerically in the test point table.

For a more in-depth analysis of the results, the voltages and currents belonging to a testpoint and the relay´s reaction (switching of output contacts) can be graphically displayed.Time measurements between different points can be made using cursors.

13

Synchronizer

In order to test a synchronizing relay, the test equipment needs to emulate the applicationin which the relay is used. Synchronizing relays are designed to measure adjoining systemswith respect to voltage phase angle, frequency, and magnitude, to safeguard against theinterconnection of two unsynchronized systems.

Synchronizer allows for a three-phase to three-phase synchronization, if a CMS 156 voltageamplifier is used together with the CMC 256/156 test set. For a single-phase to single-phasesynchronization, no additional amplifier is needed. With a CMC 256, three-phase to single-phase synchronization is possible, using the additional fourth voltage phase to represent oneof the systems.

Synchronizer can be used in single phase mode to simulate two systems to be synchronized(1 and 2). System 1 is fixed at a specified amplitude and frequency. The second voltageoutput represents system 2, i.e. the generator or system to be synchronized. System 2 iscontrolled by the software in amplitude and frequency.

The software automatically detects the circuit breaker closing command from the relay and,taking the CB closing time into account, evaluates if the synchronization takes place withinthe synchronizing window. The control of the second output is variable following differenttest modes. The frequency and amplitude can be changed linearly depending on theramping time constants of the generator.

For synchronizing devices that have automatic adjustment functions, the adjustment controlcommands (f�, f�, V�, V�) may be used to control the second voltage output. To simulatethe real system as closely as possible, a dynamic generator model is available. The binarycontact sequences of the adjustment commands, and the changes of voltage and frequency,can be monitored graphically in order to follow the progress of the synchronization.

A synchronoscope is implemented in the software, which eliminates the need for additionaltest instruments when testing synchronizing devices.

Transient Ground Fault

Transient Ground Fault tests the directional decision of transient ground fault relays. Itproduces the transient voltages and currents during a ground fault from a fault simulationwith a pre-defined network model. The network simulation provides testing with realisticcurrent and voltage waveforms. The model simulates a spur line. The calculated quantitiesare determined by the parameters of the line and the feeding network.

For testing the directional decision of steady-state ground fault relays, the steady-state faultquantities after the decay of the transient process can be continuously output.

To allow for the testing of relays in both the forward and the reverse direction, the fault canbe applied on different feeders.

The module performs an automatic assessment of the measured data based on the user´sspecific application. The output signals are shown in a separate view. They can also bedisplayed or printed with the automatically generated test report. The test execution can bemanually initiated or synchronized by using an external trigger signal.

The module is of particular assistance when • setting the relays, • checking the relay´s directional characteristic.

Both three-phase systems and two-phase systems (e.g. some railway systems) can besimulated.


14

SSooffttwwaarreeAdvanced Distance

Advanced Distance provides advanced functionality in addition to the base functionality ofDistance:• Search and Check tests• Test settings relative to zone reaches and line angle ("relative shots")• Testing multiple fault loops

Shot tests, Search tests, and Check test

At a Shot test (the only mode provided in the Distance module), test points in the test pointtable are automatically processed.

At a Search test, zone reaches are determined automatically. Zone transitions are searchedalong search lines specified in the impedance plane, using an optimized algorithm. It ispossible to define a series of search lines in a single step. All defined search lines are storedin a table for automatic processing.

At a Check test, test points are automatically set at the tolerance boundaries of zones. Thesetup is done with test lines (check lines) similar to a search test, but test points are only setat the intersections of the check lines with the zone tolerances. The Check test is an efficientoverall test of the relay with minimum testing time. This gives a quick verification of whetherthe specifications are met, particularly for routine tests.

Adding test points and test lines to the tables is possible in a variety of ways. Parameters canbe precisely defined by numerical inputs, or specified by pointing to certain locations in thecharacteristic diagram. A magnetic cursor supports the choosing of useful values. Mousecommands, context menus and keyboard shortcuts facilitate data input.

A test in Advanced Distance can have any combination of Shot, Search, or Check tests. Attest execution, the whole test settings are processed sequentially.

This versatile system offers a wide range of testing possibilities. Using this, it is easy to complywith testing philosophies and regulations.

Relative Test Definitions

A revolutionary feature is that the test settings can be made relative to the characteristic of thedistance relay. Test points are not entered in absolute R, X, Z, or angle values, but are insteadreferred to zone reaches and the line angle. The relative settings can be applied to reaches andto angles, either combined or individually.

Test points defined relative to zone reaches (e.g. 90 % of zone 1, 110 % of zone 1, 90 % of zone2, …) have the magnitude of the impedance automatically adjusted to the actual valuesdefined in the test object data.

Test points and test (search/check) lines defined relative to the line angle are twisted accordingto the setting of the line angle in the XRIO test object file.

With this feature, re-usable test templates that adopt themselves to the actual relay settingscan be created.

Constant Source Impedance Model

In addition to the constant test current and constant test voltage models from Distance,Advanced Distance provides the constant source impedance test model which is useful inspecial cases where parameters such as SIR (Source Impedance Ratio) are important.


15

Load Current

To verify special behavior of certain relays which occurs only when a prefault (load) currentis present (e.g. accelerated tripping performance), a load current can be superimposed.

Testing multiple fault loops in one test module

Advanced Distance provides special support by performing the tests for multiple fault loopswithin one test module. For all test modes (shot, search, check) multiple tabs are providedwith a separate test point table for every fault type. For every fault type, individual testsettings can be made, but for the common case of equal settings in related fault types, thereare functions to make the same settings in multiple fault types simultaneously.

Multi-windows user interface

The user interface can be configured individually, using the following elements:

Test ViewThis view holds the test point tables for the Shot, Search, and Check tests and the impedanceplane. Test definitions are made in this view. During and after the test execution, this viewdisplays the results numerically in the tables and graphically in the impedance plane.

Z/t DiagramThis view shows the graded trip time curve over the impedance along a certain line. Theactual line is determined by pointing in the impedance plane or by a selection in one of thetest tables. It is also possible to define test points and view the assessments in the diagram.

Vector DiagramThe vector diagram shows the phasors of the voltages and currents, both for the phasequantities and the sequence components. The corresponding numerical values are displayedin the attached table.

Time Signal ViewThe voltages, currents, and binary signals after a completed shot are shown in this view. Thisis useful to perform more detailed investigations (e.g. time measurements using cursors).

VI Starting

Advanced Differential

Advanced Differential is a set of test modules which form a complete testing solution fordifferential schemes. It is particularly suitable for transformer differential schemes with up to3-windings and up to 9 currents to be injected.

Extensive modeling of the protected object (power transformer), the secondary equipment(CTs, CT connection) and the relay characteristics provides the data for the computationsrequired to facilitate testing. The automatic calculation of the test currents eliminates themost time consuming and error-prone manual tasks. Testing the correct operation of therelay becomes simple, time saving, and cost efficient.

This test solution provides:• Testing with all fault types (L-N, L-L, L-L-L)• Shot tests at pre-defined test points or search tests• Evaluation and assessment of results against characteristics and tolerances• Report generation including graphical representation of the results in the characteristic

diagrams• No blocking of voltage related functions required (important for testing of

multifunctional relays)

For transformers, automatic calculation of currents to be injected are based on:• Transformer data (nominal data, vector group)• CT ratios and connections• Fault type• Fault/supply side (primary, secondary, etc.)• Load current• Amplitude and phase correction

For the protective relay, the assessment of the measured values is based on:• Operating characteristic• Bias calculation• Zero sequence elimination

If a suitable combination of test set and amplifier is used, the modules can control up to9 currents for comfortable testing of three winding transformer protection.

For non-transformer applications, such as testing generator differential protection, thecurrent calculations are done without the transformer model. These test modules are alsosuitable for testing other differential relay functions such as an overcurrent back upprotection function or an overload function integrated into the relay.

The four test modules in detail:

Diff Configuration

This module simulates through-faults to verify that the protection is stable for faults outsidethe protected zone. Since investigation of the stability may require the observation ofmultiple measurements, the module gives the tester the option to check the readings beforeproceeding with the test. The actual values read from the relay under the fault conditions(operating or restraint currents of the different phases) can be entered for full documentationin the report.

The test module Diff Configuration tests: • Secondary wiring and interposing transformers (electromechanical and numerical relays) • Correct parameter setting of digital relays (specification of protected object)• Zero-sequence elimination

17

Diff Operating Characteristic

The Diff Operating Characteristic module tests the operation of the protection for faultsinside the protected zone.

The currents injected into the relay are calculated from ldiff/Ibias value pairs specified in theldiff/lbias plane. This relates directly to how manufacturers commonly specify the operatingcharacteristic. The correct reaction of the relay, either trip or no trip, is assessed against thespecified characteristic.

Diff Trip Time Characteristic

This module tests the dependency of the trip time from the magnitude of the differentialcurrent.

Diff Trip Time Characteristic measures tripping times at specified differential currents. Theactual current configuration for a particular differential current is automatically calculated.The test points are defined in the trip time characteristic diagram and the measurements areassessed against this characteristic.

Diff Harmonic Restraint

Diff Harmonic Restraint tests the inrush and CT saturation blocking function of a differentialrelay. Currents with superimposed 2nd or 5th harmonics are injected for this test. The testpoints are defined in the harmonic restraint characteristic diagram, where the differentialcurrent is drawn over the harmonic content of the test current.

For simulating different inrush conditions, the initial phase shift between fundamental andharmonics can be specified.



SSooffttwwaarree

18

Harmonics

Harmonics produces harmonics with frequencies up to 1000 Hz with even and oddharmonics up to the 20th harmonic at 50 Hz or 16th harmonic at 60 Hz.

Harmonic signals can be output directly or exported as COMTRADE files.

The fundamental for three voltages and three currents as well as mixtures of harmonics forany of the voltage or current channels can be defined. The THD (total harmonic distortion)of the signal (for each channel) is indicated.

In static output mode the tool puts out values as long as it is in the ON condition.

In sequence mode a sequence consisting of three states can be injected:1. Pre signal: only fundamental wave2. Signal: set signal including harmonics3. Post signal: only fundamental wave

A timer starts at the moment of harmonic injection and stops on a trigger event. Theresponse time is indicated.

TransPlay - Transient Playback Utility

TransPlay as a utility program allows the loading and playback of transient files containingvoltage and current analog transient waveforms. Files which are converted from COMTRADEto WAV format can be automatically played back. This results in the injection of these signalsinto the relay. These signals may be simple harmonic waveforms or actual power systemfaults recorded from a digital fault recorder or from a simulation program, such as EMTP.

The software supports the following file formats: • IEEE COMTRADE• Windows WAV

TransPlay also includes synchronizing capability for use with an external trigger. An externaltrigger, such as a time pulse from a GPS satellite receiver (i.e. CMGPS), can initiate theplayback of a transient file at a specific time.


19

Advanced TransPlay

Ideal tool for• troubleshooting with fault records• relay evaluation with transient files (e.g. EMTP calculations)• End-to-End testing

Advanced TransPlay is a universal tool for using the CMC system to test with transient signals.

Transient signal data, obtained from fault recorders or network simulation programs, can beloaded and viewed, processed, and replayed with Advanced TransPlay. The reaction of theprotection device tested with such signals is recorded and assessed, and a test report isgenerated.

COMTRADE (C37.111-1991 and P37.111/D11), PL4 (PC formatted ASCII), TRF and CSV fileformats are supported by Advanced TransPlay. After a transient file has been loaded, the partof the signal to be replayed is selected by markers; irrelevant parts are hidden. It is possibleto repeat parts of the signal, e.g. for extending the pre-fault time. Markers can be set in orderto point out significant events in the recording, such as fault inception, starting, tripping,etc.. These markers are the basis for time measurements.

Advanced TransPlay not only plays back voltage and current signals, it also can replay thebinary signals in a fault recording via the CMC´s relay and transistor outputs. Additionalbinary signals (e.g. carrier send/received signals from communication-based schemes) can beadded.

During playback, the selected voltage, current, and binary signals are applied to theprotection device. If necessary, playback can be synchronized via GPS or by a time pulseapplied to a binary input.

The reaction of the protection device is measured and assessed on the basis of timemeasurements. Absolute and relative time measurements are possible:• Absolute time measurements determine for instance starting or trip times of the relay

during signal playback.• Relative measurements compare the relay´s reaction during playback to its behavior stored

in the recording (reference).

This makes it possible to investigate:• if the relay scatters (differences between recording and actual behavior during playback).• how a different protection device operates under the same conditions.

Advanced TransPlay provides a repetition mode; the individual results for each repetition, aswell as average and standard deviation values (statistic functions), are displayed.

(for CMC 256)


CB Configuration

For many protection relays, it is necessary to have the auxiliary contacts of the circuit breaker(CB) connected and operating for proper functioning. The CB simulation, running in aCMC 256, simulates the auxiliary contacts during a test. Depending on the available binaryinputs and outputs, it is possible to simulate one-pole and three-pole operation of the CB. Atime signal display shows the actual situation.

The CB Simulation consists of two items:• The CB Configuration module that is used to specify the timing parameters and mode of

operation of the CB Simulation. It can be used either as a stand-alone module orembedded in the OMICRON Control Center.

• The CB Simulation is running in the CMC firmware. It performs actuation of the auxiliaryCB contacts (52a, 52b) in response to trip and close commands.

Binary I/O monitor

Binary I/O Monitor displays the status of all binary inputs/outputs of the connected test set(s).It can also indicate transient changes that occur between regular updates of the displayedinformation. This is very useful during the creation of a test sequence or for troubleshooting.A hold function enables the user to freeze the display for detailed investigations. In particularwhen working with the CMB IO-7 (with its large number of binary inputs and outputs) thistool provides considerable benefit.

A typical application is the testing of the control logic of a bay control device.

Main functions:• All connected binary inputs and outputs are monitored • Runs in parallel with any OMICRON test module • Transient changes can be indicated through the "Indicate state change” function • Display can be frozen by the "Hold” function • Display names assigned in the Hardware Configuration are displayed as labels for the state

indicators

SSooffttwwaarreeAnnunciation Checker

Today´s protection devices emit hundreds of different status signals or measured analogvalues. Each signal can be displayed at various locations.

Annunciation Checker helps the commissioning engineer to verify that the allocation of eachmessage to its expected location (marshalling) and the wiring has been done correctly.

A test specification can be created prior to the test and can also be flexibly adapted while atest runs. The test specification is done in a signal/location grid.

Signals stimulate a protective device and are generated as shots or steady states. The testengineer can navigate through the test grid in any order (e.g. signal by signal or location bylocation). Each cell of the grid corresponds to a signal indicator at a certain location. Theresponse of the indicator is evaluated manually. The test results are summarized in a tabulartest report.

21

NetSim - Network Simulation Software

This test module brings power system network simulations and testing with transient signalswithin the scope of the commissioning engineer and the routine tester. Standard networkconfigurations with a simple parameter setup provide instant "click and run" simulations withsignal output via the CMC test set.

Applications• Relay testing under real-life conditions• Evaluation of relay settings for difficult protection applications• Testing of advanced protection algorithms• Easy End-to-End testing of line protection with GPS time synchronization

The transient voltages and currents are calculated from a digital network model, providingoptimal approximation of the real events in a power network.

Test Cases• Short circuit events on single lines, parallel lines (including mutual coupling), and three

terminal lines• Power Swings

Customized test cases can be produced on request.

Event Simulation• Fault types L-E, L-L, L-L-E, L-L-L, L-L-L-E• Selectable fault location• Selectable fault resistance (arc simulation)• Simultaneous faults on parallel lines• Open phase• Spur line• Switch-onto-fault• Power Swing• Automatic repetition of tests with varying parameters• COMTRADE export for simulated waveforms

The simulation of the power system takes all essential components and parameters intoaccount, as:• Voltage sources• Lines, mutual coupling• Circuit breakers• CT saturation

Power Swing TestingThe realistic power system quantities generated by NetSim are essential for successfullytesting advanced power swing blocking functions in modern relays, where simple impedanceramps or sequences of impedance states will mostly fail. Asynchronous power swings canalso be generated with multiple pole slips for effectively testing Out-of-Step (OST) functions.The synchronous power swing test case simulates a transient oscillation that returns to astable state.

Three Terminal LineDue to obvious cost benefits, tapped lines become more and more frequently installed.Depending on impedance values (e.g. cable tap on overhead line) or topographical layout(e.g. tap close to one end), distance protection may have serious reach problems with thisconfiguration. The three terminal line configuration is an ideal test case for investigating theconditions on tapped lines. Finding optimized protection settings for this difficult case issubstantially supported.

Meter

OMICRON´s approach significantly simplifies the testing of energy meters. Until now, theusual method has been to use a stabilized, but not very accurate, power source, incombination with a reference meter.

By using state of the art hardware technology, OMICRON provides test sets that are soaccurate and stable, that the signal source itself represents the reference (applies especiallyto the extended precision (EP) option of CMC 156 or CMC 256 test sets). This makes areference meter unnecessary for most cases. The CMC test sets not only provide the testsignals, but also have inputs for the meter pulses allowing closed loop testing. To this end,optical scanning heads for capturing pulses emitted by infrared LEDs are available.

Meter allows for manual or automated testing of energy meters. The automatic test iscontrolled by a test point table.

Each line of this table represents a test point, which can be run in one of the following modes:Load test Accuracy of measurement unit (time power method)Mechanism test Accuracy of entire meter including displayGated Mechanism test Testing internal meter registersInjection test Quick check (wiring, sense of rotation)No-load test No start-up at zero loadCreep test Start-up at low loads

In the columns of the table the individual test parameters, the set assessment criteria(tolerance, nominal behavior), and the result of the test, including the assessment (passed orfailed), are displayed. For multifunctional meters, or meters with two directions of rotation,a table per test function is available (multiple tabs). Test lines can be repeated several times.In this case the standard deviation is displayed together with the meter error, which allowsconclusions of the correctness of the test itself. Single test steps (e.g. those assessed as failed)can be repeated after a test run is finished, without the need for repeating the whole test.

For testing the meter´s behavior with harmonics or dc components, the following currentsignal waveforms are available:• Sine• Sine + Harmonics• Sine + dc

The test quantities are displayed graphically by means of the voltage, current and powervector diagrams on the right of the screen.

The test can by performed with any balanced or unbalanced load for:• Single phase meters (or a single measurement element of a 3-phase meter)• 3-wire meters• 4-wire meters

All parameters can be specified in a detail view independently for each phase. Apparent,active and reactive power is indicated for each phase and the whole rotary system. Testingof the following meter functions is supported:• Wh importing/exporting• varh importing/exporting• VAh• I2h and U2h (load/no-load losses of transformers)• Qh (Quantity hour)

The results of an automatic test are clearly summed up in a tabular test report (one line pertest point). For a manual test, generating any test quantities, without defining a completetest procedure, can quickly check the correct functioning of meters. In this mode theconstant of a meter can also be determined, in case it is not known or if there are doubtsabout it.

When testing with a reference meter, the CMC is used as a current and voltage source.During a load test the pulses of the meter under test, as well as those of the reference meterare registered. The latter form the reference for error calculation.

Furthermore, testing against a 0.02 or 0.01 % reference before a test is run, using the sametest points, can eliminate errors of the CMC.


23

Transducer

The software module for testing measurement transducers allows for manual or automatictesting of any measurement functions, such as• Real power single- or three-phase• Reactive power single- or three-phase• Apparent power single- or three-phase• Frequency• Current• Voltage (phase-to-ground, phase-to-phase)• cos ϕ• Phase angle (V-I, V-V, I-I)• dc quantities (current, voltage, power)• Signed average of currents

The module supports testing of the following types of characteristics:• Linear• Compound• Quadratic• Symmetrical or non-symmetrical

The definition of the characteristic corresponding to the test object settings is easy and isdisplayed graphically. A default test setting is derived from the test object definition,facilitating the definition of an automatic test of the transducers characteristic.

The "manual test” mode is used, if a measurement transducer is to be readjusted. Every desiredinput quantity can be generated for the transducer. Furthermore, it is easy to switch betweensignificant points of a characteristic, where the error of the transducer is shown at a certain inputvalue.

An automatic test includes the sequential output of a pre-defined test point table, as well as thedocumentation and assessment of the results.

Here, the test points represent the input value of the measurement transducer. In addition,the behavior at changing input voltage or frequency can be performed as an option.

The error of a transducer is determined by comparing the theoretical signal and the actuallymeasured output signal. Relative, absolute and class errors are derived and graphicallydisplayed in a diagram. If multiple test runs are performed, the average error is indicated.

Single test points or test sequences can be added to the test point table. The table includes:• Input value• Output value• Class error• Assessment (test passed or failed)

During the automatic test run all test points are processed in a sequence. The transfercharacteristic including all test points (passed or failed) is displayed graphically. If remotedisplays should be checked during the test run, the test can also be controlled manually.

Measuring transducers for three-wire (Aaron circuit) as well as four-wire systems can betested. Current as well as voltage can be generated as pure sine signals or superimposed withharmonics or dc components.

New generation transducers often no longer have classical mA or Vdc output. They rathertransmit the measured data via transfer protocol or/and visualize values at a display. Themode "open loop testing" supports testing this type of transducer.

To achieve higher accuracy for calibration and testing it is recommended that the EP(Extended Precision) option of the CMC 156 or the CMC 256 is used.

24

SSooffttwwaarreeEnerLyzer

EnerLyzer is a software option for the CMC 256, enabling powerful analog measurementfunctions. With this option, each of the ten binary inputs can be reconfigured for use asanalog measurement inputs. Thus a CMC 256 together with EnerLyzer becomes amultifunctional measurement and recording unit.

EnerLyzer can be used concurrently with any active Test Universe test module.

Voltages of up to 600 Vrms can be measured. Alternatively, currents can also be measuredby using current clamps with voltage outputs or measurement shunts. Five measurementranges make use of the optimal accuracy, matching the signals to be measured. Themeasurement data can be displayed as secondary or primary values. Results can besummarized in a measurement report.

Multimeter

In this mode, all ten inputs can either be used as voltage or as current inputs. Ac or dc valuescan be measured. For ac, two different frequencies can be determined (e.g.generator/network).

EnerLyzer displays the following quantities:• rms value and phase for V, I (ac)• Symmetrical components • Line-to-line voltage• Two frequencies• Active, reactive, and apparent power per phase and three-phase• cos ϕ• dc values for voltage, current and power

Harmonic analysis

This mode allows the on-line analysis of a signal up to the 64th harmonic (at 50/60 Hz).

EnerLyzer displays the following quantities:• rms value and phase of the fundamental• Frequency, rms value and THD of the overall signal• rms value and phase of the harmonic

Signals can also be captured using a "snapshot” function and displayed graphically.

Transient recording

With EnerLyzer, the CMC 256 can be used as a powerful 10 channel transient recorder. Themaximum recording time depends on the sampling rate and on the number of channels tobe recorded (one channel recorded at 3 kHz yields a recording time of over 5 min.). Eachrecording is stored in COMTRADE format.

Sampling rate, pre-trigger time and recording time can be set for each recording.

Recording may be triggered manually or by a defined trigger. This can be a certain voltage,current or binary level with rising or falling slope, or a certain power quality phenomena.

Power Quality Triggers

Different power quality criteria can be combined to trigger signal recording:• Swell & Sag triggers: Trigger when a certain swell or sag occurs in a certain channel. • Harmonic: Triggers when either a certain harmonic or the total harmonic distortion

exceed a certain level specified as a percentage of the nominal value.• Frequency: Triggers when the frequency goes outside the specified deviation of the

nominal frequency in Hertz. • Frequency Change: Triggers when the rate of change of frequency exceed the specified rate.• Notch: Triggers after a certain number of notches of a certain duration and amplitude

occur.

Trend Recording

Records the following quantities over time:• Frequency 1 (any channel)• Frequency 2 (any channel)• Currents (rms value)• Voltage (rms value) • Phase angles • Real power (single and three phase) • Reactive power (single and three phase)• Apparent power (single and three phase)• cos ϕ

Each type of quantity (e.g. frequencies, currents, or real powers) is displayed in a separatediagram over time.

The amount of samples in all charts together is limited to 4 million. If the limit is exceededrecording is continued and the oldest samples are removed from the chart.

Measurements over a very long period of time are possible by choosing a large measurementrate - setting a rate of 10 s will allow a continuous measurement over several weeks.

Visualization and in-depth analysis of transient recordings can be performed with TransViewprovided with EnerLyzer. Replaying of transient recordings is possible using either AdvancedTransPlay or TransPlay.

EnerLyzer supports the binary input/output unit CMB IO-7.

SSooffttwwaarreeTransView

TransView is a software for visualization and analysis of recorded analog and binary signals,often transients in the network, which were recorded with transient recorders (relay-internalrecording, CMC 256 EnerLyzer, disturbance recorder). It processes the recorded datagraphically and calculates further quantities of the energy system out of the measurementdata, like impedances, power vectors, rms values, etc..

The quantities can be represented as primary or secondary values in different views:• Time signals• Vector diagrams• Locus diagrams• Harmonics• Value tables

For the analysis of a transient recording, amplitude and time measurements can beperformed using two cursors. The voltage and current values on the cursor positions aredisplayed in the vector diagram or the value table.

The zoom function allows the representation of the values in every view with optimal scale.

TransView allows for simultaneous analysis of multiple recordings, e.g. of the two ends of aline.

Time signalsHere analog and binary signals are represented as a function over time. Analog quantitiescan be displayed as instantaneous or rms values.

Vector diagramsThis view visualizes measured and calculated quantities (e.g. symmetrical components) ascomplex vectors at defined points in time.

Locus diagramsThis view visualizes complex quantities as locus diagrams. Impedance locus diagrams can berepresented together with tripping zones of distance relays. Zone settings can be importedusing the XRIO format.

HarmonicsThe Harmonics view shows the rms values of harmonics of selected measured quantities asbar graphs. The amplitude values are given in absolute values and as a percentage of thefundamental. The harmonics are determined using a full-cycle DFT (Discrete FourierTransformation).

Value tableThe Table view shows the values of several signals at the cursor positions. The signals arearranged in rows, where the individual columns contain the respective values.

TransView supports data in COMTRADE format (IEEE Standard Common Format for TransientData Exchange for Power Systems).

Ba Pr AP Me Mt Un� � � � � �Field Calibration Software cm_FCS

The Field Calibration Software cm_FCS supports users when performing a calibration or a selfcheck. A number of test templates are available for CMC 256 and CMC 156/151 test sets.A calibration can be performed with any suitable reference device with sufficient accuracy.

CMC 256 users can perform a self check utilizing the CMC test set´s own analog measuringinputs. The number of included test points can be adapted according to the users´ needs.

The software guides the user through the procedure and provides a calibration report. Beforea unit is sent back to OMICRON for a factory calibration (always includes a readjustment) afield calibration using cm_FCS shall be performed at the customers location. As long as theresults documented in the calibration report are within specifications there is no need for afactory calibration.

CMC test sets have very little drift over many years and thus the need for a factory calibrationarises only very rarely.

SSooffttwwaarreeScheme Testing Tools

OMICRON´s Scheme Testing Tools is a suite designed to test various logic schemes found inmodern relays, meters and IEDs. It consists of CommPro and LogicPro for line protection logicscheme testing, DLogicPro for distribution protection logic scheme testing and PQPro forpower quality logic scheme testing. These tools eliminate the complexity of testing theseschemes and provide four distinct operational benefits:

Benchmark TestingUsing standardized tests and a given set of device settings, the test engineer can evaluatethe complex logic of different protective relays, meters, or IEDs and how they interact withinthe communication-based or logic-based scheme chosen. This permits direct comparison ofdifferent manufacturers´ implementation of the same logic schemes, making acceptancetesting much easier.

Training ToolThe fault and logic sequence of the selected scheme can be reviewed through the AnimationMode. The Test Objectives and Hardware Requirements views provide information about thedifferent stages executed by the CMC system and the fault stimulation utilized.

Single Scheme TestThe software performs several essential tests, which can functionally check the relay´sresponse while operating in a communication-based or logic-based scheme mode. These arebased on user defined line parameters, fault location, and time settings, which reflect theactual application in use.

Multiple Scheme TestsThis feature allows several schemes to be tested in sequence, prompting the test engineer tochange the communication scheme setting or logic option in the device, if necessary, tocontinue the tests. Printing options of all relevant settings, test objectives and automatic testresults are available.

CommPro

CommPro is designed to test 9 communication-based schemes in transmission line distancerelays. It simulates pre-fault, fault and post-fault conditions, breaker and communicationsequipment signals. It monitors the operation of relay distance elements and sending ofpermissive or blocking signals. Schemes include:

• Direct Underreaching Transfer Trip• Directional Comparison Blocking• Permissive Underreaching Scheme• Current Reversal Logic Scheme• Permissive Overreaching Scheme• Weak Infeed Logic Scheme• Permissive Underreaching Unblocking• Echo Logic Scheme• Permissive Overreaching Unblocking• Current Transformer Supervision

29

LogicPro

LogicPro is designed to test 14 non-communication based schemes in transmission linedistance relays. It simulates the System Fault conditions, Single or Three-Pole Breaker statusand other control signals. It monitors different relay scheme logic elements and single orthree phase trip signals. Schemes include:

• Switch-onto-fault• Power Swing Trip• Remote End Opened• Power Swing Block• Loss of Potential• Pole Dead Logic• Load Encroachment• Evolving Fault• Zone 1 Extension• Block Reclosing• Single Pole Tripping• Breaker Failure Protection• Stub Bus Protection• Current Transformer Supervision

DLogicPro

DLogicPro is designed to test logic schemes found in distribution feeder protection relays. Itcontains 13 of the most typical schemes, (Cold-Load Pickup, Fuse Saving, CT & VTSupervision, Feeder Blocking, Sympathetic Trip Logic, Broken Conductor Detection, SelectiveOvercurrent Logic and Backup Tripping, Switch-onto-fault, Breaker Failure, Block Reclosing,and Bus Protection Logic) found in feeder protection. It includes test objective, schemeanimation, hardware connections, and test case execution where the power system issimulated by the CMC.

PQPro

PQPro is the fourth tool in the Scheme Testing Tools Suite and offers multiple advantages asa power quality training and evaluation tool. It contains 13 of the most common powerquality logic detection schemes and gives the user the ability to understand and test thesepower quality monitoring functions that are based on fundamental frequency components.

A main concern of sensitive industrial, manufacturing facilities and utilities are voltagevariation events that may result in service or process interruptions resulting in significantlosses. Industries define their own voltage variation withstand characteristics usually inaccordance with a specific operational or design standard (like the CBEMA curve in the USA).The default settings for the Sags and Swells are based on IEEE 1159. However, for all the teststhe user can enter their specific settings based on the standard being used and make themthe default since they are saved in a separate file. PQPro contains the following tests:

• Instantaneous/Momentary/Temporary voltage sag• Instantaneous/Momentary/Temporary voltage swell• Short/Temporary/Sustained voltage interruption• Power factor/Voltage/Frequency variation• Voltage unbalance

IEC 61850 and UCA 2.0 Testing Solutions

The GOOSE Configuration Module and GSSE Configuration Module extend the capabilities ofthe OMICRON protection testing solutions to applications with real-time messaging insubstation communication networks. The modules perform the subscribtions and simulationsof the messages and set up the mappings between the binary I/Os of the test set and thestatus indicators in the GOOSE or GSSE messages.

The standard IEC 61850 describes the communication of devices in substations. Oneimportant issue relevant to protection specialists are the real time (process bus) protocols fortransmitting binary status and sampled value data.

For testing, the protection engineer needs access to these data. GOOSE (Generic ObjectOriented Substation Event) messages transport binary status signals over the substationnetwork and are also used for tripping and interlocking. This mechanism is an extension ofthe GSSE (former UCA GOOSE) used with UCA 2.0.

The NET-1 hardware option for OMICRON CMC 256 test sets is required for protectiontesting with Ethernet-based substation communication protocols, the GOOSE ConfigurationModule and GSSE Configuration Module can only be used with the NET-1 hardware option.

Protection and Communications

Protection engineers are increasinglyaffected by communication issues.Connections via classical SCADA protocolssuch as DNP and IEC 60870-5-103 providedadditional information and features to beused by the SCADA system, while thesignalling for the core functionality was stillperformed by hard wired binary contacts.Nevertheless, there are many issuessurrounding the interface betweenprotection and SCADA, which requireanalysis and testing to investigate problemsand verify proper functioning.

Recently, with the advent of network basedtechnologies according to IEC 61850utilizing real-time status signalling viaEthernet, even mission critical informationmay be sent over the communicationnetworks. There are also devices accordingto the UCA 2.0 specification which operateon this principle. Having access to theinformation on the substation networkbecomes a necessity for performingprotection testing.

Making use of leading-edge technology in both development and quality assurance, OMICRON has set new standards for advanced three-phase testing equipmentin terms of flexibility, accuracy, portability and reliability.

OMICRON´s PC-controlled test sets generate the test signals digitally (DSP technology), resulting in highly accurate testing signals even atsmall amplitudes. The electronic design of the internal amplifiers and the use of switch-mode power supply units ensure a minimum ofweight and volume. Independent channels with low-level signals are available at the back of the test sets, which can be used to controlexternal amplifiers for applications requiring more signal channels or higher currents, voltages or power. The low-level signals can also beused for test objects which have a low-level input facility.

All generators are continuously and independently adjustable in amplitude, phase and frequency. No switching of ranges is necessary. Allcurrent and voltage outputs are fully overload and short-circuit proof and are protected against external high-voltage transient signals andovertemperature.

Every device is developed according to international IEC standards and verified by independent certification bodies including UL and TÜV.

CMC Test Set Options

EP(ExtendedPrecision)

Available for CMC 256 and

CMC 156

Equipped with the hardware option EP (Extended Precision), a CMC test set becomes anideal instrument for the testing of energy meters. Due to the extremely high accuracyof the EP option, it is possible to test energy meters of up to class 0.2S according toIEC 62053 (formerly 60687, 0 ... 300 V three-phase for a CMC 256-EP) without anadditional reference meter. This extremely high precision also makes a CMC 256 orCMC 156 ideal for relay manufacturers for their development process, type testing,acceptance testing, device calibration, or product demonstration.

The technical data section on the following pages provides detailed information onwhere a EP version differs from a standard CMC.

The EP option can be ordered together with a new unit or an existing CMC 256 or CMC 156 can be upgraded at any later stage.

NET-1

Available for CMC 256

Several developments in computer and communication technologies have created a needfor alternative communication interfaces in protection test sets.

The new way of controlling the test set is performed via Ethernet. This proven networktechnology offers many new opportunities in excess of just replacing the parallelinterface, like controlling the test set over a network.

Another advantage is the support of substation communication according to IEC 61850and UCA 2.0. These protocols are also based on Ethernet.

The NET-1 option for CMC 256 replaces the parallel interface and provides the newcontrol interface for the test set. It is required for interfacing to Ethernet-basedsubstation communication protocols.

The NET-1 option has two Ethernet interfaces:• 10/100 Mbit/s "copper" (10/100Base-TX, auto-sensing, auto-crossover, RJ45 connector

for CAT5 twisted pair cables).• 100 Mbit/s fiber optic (100Base-FX, MTRJ connector). Support for specific substation

protocols, such as the GOOSE/GSSE messaging according to IEC 61850-8-1 or UCA 2.0can be provided by future firmware options.

On the PC controlling the test set, this option requires Test Universe Software Version 2.0running on Microsoft Windows 2000 or Windows XP operating systems.

The NET-1 option can be ordered with a new device or as an upgrade for a CMC 256.Test sets with the NET-1 option no longer have a parallel port interface.

1 The CMC 256 can have both options, EP and NET-1, simultaneously installed.

CMC 151 upgrade to CMC 156 VE001010

CMC 151 ordering options:

The high power amplifier units CMS 251 and CMS 252 allow the testing of even the highestburden electromechanical relays of all types (overcurrent, undervoltage, ground fault relays, etc.).The single-phase CMS 251 and the two-phase CMS 252 provide dual mode amplifiers thatcan independently function either as a voltage source or as a current source (user selectable).

Application exampleRequired voltage waveshape for an electromechanical inverse time earth fault relay,plug-setting 0.2 A, test current: 2 A.

38

Recommended for tests requiring• higher currents/power in the current path.• more than 3/6 current channels (e.g. for testing 3-winding transformer differential

protection).

The CMA 156 contains 6 independent current channels, arranged in two isolated groups (A, B).By connecting all six current phases in parallel, for example, a power of up to 420 VA and currentup to 150 A can be delivered, which allows testing a wide range of electromechanical relays.

Recommended for tests requiring• higher currents/power in the current path • more current channels

For three-phase applications the outputs provide a range of 0 to 50 A at a maximum powerof 140 VA per phase. In single-phase applications an output power up to 420 VA and acurrent up to 150 A is possible.

Recommended for tests requiring• higher current/voltage. • higher power in the voltage/current path.• up to 9 (with CMC 256) independent current phases (e.g. for testing differential relays) or • 6 independent voltage phases (e.g. for testing synchronizing devices with 6 independent

voltages).• in single-phase applications an output power of up to 210 VA and currents up to 75 A is

possible.

The extensive range of OMICRON amplifiers

The following intelligent amplifiers can be used in combination with any multiple phase CMC test set listed on the previous pages to extendthe testing range and power. Up to 4 current amplifier units can be paralleled for up to 3-phase, 200 A output. The interconnection betweenthe CMC and the amplifier units is effected by means of a control cable to be connected at the back of the units. The outputs of the amplifierunits are galvanically separated from the input and the ground and can be used independently and additionally to those of the CMC 256/156(e.g. for differential protection testing). Amplifier outputs can be configured in various ways (connected in parallel, serial, etc.).

Polarity Checker checks a series of terminals for correct wiring (replacement for batterychecking method).

A special continuous test signal (voltage or current) is injected at one point with the CMC.Then the polarity at all terminals can be checked with CPOL as shown below.

Following this procedure provides a clear indication as to whether the polarity is OK (greenLED) or not (red LED). This procedure is much faster than the conventional method and caneasily be performed by a single person.

The polarity checker utility comes with Test Universe Software 2.0 and is enabled by theoptional CPOL polarity checker hardware accessory.

1 Error corresponds to amplifier output signals (voltage/current) of CMGPSsynchronized test sets at configured GPS trigger event5 μs: enhanced mode (CMC 256 only + State Sequencer)

When performing end-to-end tests of line protection schemes, it is necessary to start severaltest sets simultaneously. The CMGPS is a GPS-based synchronization unit which is used withthe CMC/CMB test set.

The CMGPS receives signals from the satellites of the Global Positioning System (GPS) andprovides an output at a time specified by the user. This clock output is then used as a triggerinput to start the CMC test set. The CMGPS has been developed to fulfill the requirementsof testing in the field, because off the shelf GPS-receivers have many drawbacks (size, weight,complicated operation, etc.).

CMGPS is typically ready for operation just 5 minutes after start up. The synchronizing pulsecan be configured according to the requirements of the application. The software is bothintegrated in the testing modules (like the State Sequencer) and also provided as a stand-alone application. It allows for the setting of: first output pulse, pulse rate, and polarity.

Two independent timing pulses are available via separate connectors, on a 16-pin plug (Pulseout 1) which is connected to the CMC test set (ext. interf.) and on two 4 mm banana plugs(Pulse out 2).

CMLIB A can be used for tapping the analog low level signal outputs of a CMC and/or forconnecting with the control inputs of amplifiers like CMA 156 and CMS 156.

Applications: • Connection of the low level signal outputs of a CMC to a relay with low level signal inputs

(unconventional transformer, Rogowski) • Connection of any external amplifiers (which do not have an OMICRON connection socket)

to the CMC low level signal outputs • Connection of OMICRON amplifiers to any controlling sources (which do not have an

OMICRON connection socket) • Easy additional tapping of the signals between the CMC test set and OMICRON amplifiers

The CMLIB A standard delivery contains the following connection material:• 16-pin "CMC" connection terminal to connect CMLIB A to the generator outputs of a

CMC 156 (Gen. Out 7-12) or to a CMC 256 (LL out 1-6) • 16-pin "Amplifier" connection terminal to connect CMLIB A to external amplifiers

Accessories: connection cables can be ordered separately• BNC to BNC [VEHK0008]• BNC to 4mm banana cables [VEHK0005]

(note: ordering number includes 1 cable)

The photoelectric scanning head TK323 is suitable for scanning of all known rotor marks ofFerraris meters and for scanning of LED´s up to the infrared wavelength range. It includes aspiral cable for the connection to a CMLIB B.

For electronic meters with optical pulse outputs the magnetic scanning head TVS6.15/1(dia. 32 mm, 1,3”) is available. It can be used on most electronic meters.

Other scanning heads may be utilized at the user´s discretion. For scanning heads whichrequire a 7-pin Tuchel-connector, the adapter-cable Tuchel-Lemo is available. The CMLIB Bworks with these alternatives as well.

43

CMLIB B provides a simple way to make the connections from the CMC to the meter undertest and/or a reference meter. There are numerous types of meters with various ways ofproducing the counting pulses. The use of a dual function photoelectric scanning head is themost universal method of interfacing these differing types of counting pulses. CMLIB B wasdesigned to make this interface simply “plug-and-test”. The CMLIB B set comprises: CMLIBB, connection cable to CMC units, connection cable CMLIB B to reference meter, and a powersupply.

CMLIB B provides the following connection terminals:• 16-pin LEMO socket to connect CMLIB B to the External Interface of a CMC 256 or CMC 156 • One 2-pin socket for connecting the power supply• Two 5-pin-LEMO sockets to connect to a scanning head (TK323 or TVS6.15/1) and/or to a

reference meter´s pulse output• Five banana sockets (1-4 plus N) providing access to the transistor outputs of a CMC 256/156• Two banana sockets (fin, fRef) for connecting pulses from a meter under test and/or a

reference meter to a CMC test set (as an alternative to the 5-pin LEMO sockets)

CM ASB2 allows for easier testing of relays with higher current or power requirements.

Main applications:• Testing the I>> element (with e.g. 50 A) of an overcurrent relay per phase by paralleling

the outputs of the CMC 256• Switching up to 4 current outputs of the CMC 256 in series to gain four times higher

voltage in the current path (e.g. for testing distance, electromechanical relays).• Using a CMS 252 (1 x I, 1 x U) without re-wiring when changing phases.

The relay can be connected in a standard three-phase manner to CM ASB2, which isconnected to the CMC using a single control cable. Any 1- or 2-phase faults can be switchedwith the box.

CM ASB2 is supported by the following modules:

Manual control Automatic control• Quick CMC • Advanced Distance• State Sequencer • Distance• Ramping • Autoreclosure• Advanced TransPlay • VI starting
