Description

Application

The SIPROTEC 4 units arenumerical relays that alsoperform control and monitor-ing functions and thereforesupport the user in cost-effective power system man-agement, and ensure reliablesupply of electric power tothe customers. Local opera-tion has been designed ac-cording to ergonomic criteria.Large, easy-to-read displayswere a major design aim.The SIPROTEC 4 units have auniform design and a degreeof functionality which repre-sents a whole new quality inprotection and control.The use of a powerful micro-controller and the applicationof digital measured valueconditioning and processinglargely suppresses the influ-ence of higher-frequencytransient phenomena and DCcomponents. The protectivefunctions evaluate the funda-mental wave. The overloadprotection evaluates r.m.s.values.

Programmable logic

The integrated logic charac-teristics allow the user to im-plement his own functionsfor automation of switchgear(interlocking) or a substationvia a graphic user interface.The user can also generateuser-defined messages.

Communication

The SIPROTEC 4 units pos-sess up to three serial inter-faces:− Front interface for connect-

ing a PC− System interface for con-

necting to a control systemvia IEC 60870-5-103 orProfibus-FMS/DP, ModbusRTU, DNP 3.0

− Data transmission− Time synchronization via

binary input IRIG B/SCADA(DCF 77)

− Prepared for UCA,Ethernet

Line protection

The SIPROTEC 4 units can beused for line protection of highand medium voltage networkswith grounded (earthed), low-resistance grounded, isolated orcompensated neutral point.

Motor protection

For motor protection, theSIPROTEC 4 units are suitablefor asynchronous machines of allsizes.

Transformer protection

The SIPROTEC 4 units performall functions of back-up protec-tion supplementary to trans-former differential protection.The inrush suppression effec-tively prevents tripping by inrushcurrents.

Back-up protection

The SIPROTEC 4 units can beused universally for back-upprotection.

Control

The integrated control functionpermits control of disconnect de-vices (electrically operated/mo-torized switches) or circuit-breakers via the integrated oper-ator panel, binary inputs, DIGSI 4or the control and protection sys-tem (e.g. SICAM). They supportsubstations with single and du-plicate busbars. The number ofelements that can be controlled(usually 1 to 5) is only restrictedby the number of inputs and out-puts available.A full range of command proc-essing functions are provided.

Time synchronization

A battery-backed clock is astandard component and canbe synchronized via a syn-chronization signal (DCF77,IRIG B via satellite receiver),binary input, system inter-face or SCADA (e.g. SICAM).A date and time is assignedto every indication.

Selectable binary inputsand outputs

Binary inputs, outputs andLEDs can be assigned to per-form specific functions as de-fined by the user.

Selectable function keys

Four function keys can be as-signed to permit the user toperform frequently recurringactions very quickly and sim-ply.Typical applications are, forexample, jumps to a givenposition in the menu tree inorder to display the list of op-erating indications or to per-form automatic functions,such as “Switching ofcircuit-breaker”.

Continuous self-monitoring

The hardware and softwareare continuously monitored.If abnormal conditions aredetected, the units signalsimmediately. In this way, agreat degree of safety, relia-bility and availability isachieved.

Reliable battery monitoring

The battery that is providedis used to back-up the clock,switching statistics, thestatus and fault indicationsand the fault recording in theevent of a power supply fail-ure. Its function is checkedby the processor at regularintervals. If the capacity ofthe battery is found to be de-clining, an alarm is gener-ated. Regular replacement istherefore not necessary.All setting parameters arestored in the Flash-EPROMwhich are not lost if thepower supply or battery fails.The SIPROTEC 4 unit re-mains fully functional.

Protection functions

The SIPROTEC 4 units areavailable with a variety ofprotective functions. Pre -defined application packagescan be implemented to makeselection easier for the user.

Metering values

Extensive measured values,limit values and metered val-ues permit improved systemmanagement, as well as sim-plified commissioning.

Transducer

Uses two 4 to 20 mA inputinterfaces.

Operational indications

Indications with timestamp

The SIPROTEC 4 unitsprovide extensive data forfault analysis, as well as con-trol. All indications listedbelow are protected againstpower supply failure.n Fault signals

The last eight fault casesand 3 sensitive ground faultcases are always stored inthe unit. All fault recordingsare time stamped with aresolution of 1 msec.

n Operational indicationsAll indications that are notdirectly associated with thefault (e.g. operating orswitching actions) arestored in the status indica-tion buffer. The time resolu-tion is 1 ms, buffer size: 80indications.

Fault recording up to 5 sec-onds

The digitized values forphase currents, ground(earth) currents, line andzero-sequence currents arerecorded in a fault recording.The record can be startedusing a binary input, on initia-tion or when a trip commandoutput occurs. Up to eightfault recordings may bestored. For test purposes, itis possible to start a fault re-cording via DIGSI 4 or theconnected control and pro-tection system.

SIPROTEC 4/SICAM system/SCADA

SIPROTEC 4 as integral part of SICAMenergy automation system

SIPROTEC 4 is tailor-made for use in theSIMATIC-based SICAM energy automa-tion system.The SICAM family consists of the fol-lowing components:n SICAM RTU, the modern telecontrol

system with automation and PLC func-tions

n SICAM SAS, the modern integration ofswitchgear automation and informa-tion technology

n SICAM PCC, the information and com-munication technology on a PC basis

Software data management and com-munication is one of the strong-points ofcombining of SICAM and SIPROTEC 4.Powerful engineering tools (SICAM plusTOOLS on the basis of STEP7 andSICAM WinCC) make working withSICAM convenient. The SIPROTEC 4units are optimally matched for use inSICAM SAS and SICAM PCC.With SICAM and SIPROTEC 4 continuityexists at three central points:n Data managementn Software architecturen Communication.All central system components (SICAMand SIPROTEC 4 CPUs, SICAM WinCC,SICAM plus TOOLS, bay controllers andprotection equipment), as well as theDIGSI 4 operating program, are estab-lished on the same basis.The interface and ability to link SICAM/SIPROTEC and other components of thesubstation control, protection and auto-mation is assured via open interfaces,such as IEC 60870-5-103 or PROFIBUS.

Service bus

DIGSI 4 offers the additional possibilityof accessing bay controllers via modem.It is possible to read out from the officedesk or when travelling (by laptop andmodem) the operational and fault eventlogs, fault records, as well as opera-tional measured values of all protectiondevices of an installation. This permitsrapid and extensive access for the serv-ice personnel.

Star coupler

All SIPROTEC units operate also withthe proven star coupler. The star coupleris used for simple applications whichalso give the user an alternate methodof retrieving information remotely.

With respect to communica-tion, particular emphasis isplaced on the requirementscustomary in energy automa-tion:n Every data item is time-

stamped at the source, i.e.where it originates.

n The communication systemautomatically handles thetransfer of large data blocks(e.g. fault recordings or pa-rameter data files). Theuser can apply thesefeatures without anyadditional programming ef-fort.

n For the reliable execution ofa command, the relevantsignal is first acknowledgedin the unit involved. Whenthe command has been en-abled and executed, acheck-back indication is is-sued. The actual conditionsare checked at every com-mand handling step. When-ever they are not satisfied,controlled interruption ispossible.

Local PC interface

The PC interface accessiblefrom the front of the unit per-mits quick access to all pa-rameters and fault eventdata. Of particular advantageis the use of the DIGSI 4 op-erating program during com-missioning.

Safe bus architecture

n RS485 busWith this data transmissionvia copper conductors elec-tromagnetic fault influ-ences are largely elimi-nated by the use oftwisted-pair conductor.Upon failure of a unit, theremaining system contin-ues to operate without anyfaults.

n Fiber-optic double ring cir-cuitThe fiber-optic double ringcircuit is immune to electro-magnetic interference.Upon failure of a sectionbetween two units, thecommunication systemcontinues to operate with-out disturbance.

It is generally impossible tocommunicate with a unitthat has failed. If a unitwere to fail, there is no ef-fect on the communicationwith the rest of the system.

Retrofitting: Modules forevery type of communica-tion

Communication modules areavailable for the entireSIPROTEC 4 unit range.This ensures that a range ofcommunication protocols canbe used (DNP 3.0, ModbusRTU, UCA, IEC 60870-5-103,Profibus, DIGSI). No externalconverter is required.

IEC 60870-5-103

IEC 60870-5-103 is an inter-nationally standardized proto-col for the efficient solving ofcommunication problems inthe protected area.IEC 60870-5-103 is sup-ported by a number of pro-tection device manufacturersand is used world-wide.

Profibus-FMS

Profibus-FMS is an interna-tionally standardized commu-nication system (EN 50170)for communication problemsolving. Profibus is supportedinternationally by severalhundred manufacturers andhas to date (status as at mid1997) been used in morethan 1,000,000 applicationsall over the world.Connection to a SIMATIC S5/S7programmable controller ismade on the basis of thedata obtained (e.g. fault re-cording, fault data, measuredvalues and control functional-ity) via SICAM energy auto-mation system or viaProfibus DP.

Profibus DP

Profibus DP is an industryrecognized standard forcommmunications and issupported by a number ofPLC and protection devicemanufacturers.

Measured values

The RMS values are calculated from theacquired current and voltage along withthe power factor, frequency, active andreactive power. The following functionsare available for measured value proc-essing:n Currents IA, IB, IC, IN, IEE (67Ns)n Voltages VA, VB, VC, VAB, VBC, VCA

n Symmetrical components I1, I2,3I0; V1, V2, 3V0

mum current and voltage valuesn Operating hours counternMean operating temperature of over-

load functionn Limit value monitoring

Limit values are monitored using pro-grammable logic in the CFC. Com-mands can be derived from this limitvalue indication.

n Zero suppressionIn a certain range of very low meas-ured values, the value is set to zero tosuppress interference.

Metered values

For internal metering, the unitcan calculate an energy meteredvalue from the measured currentand voltage values. If an externalmeter with a metering pulse out-put is available, the SIPROTEC 4unit can obtain and process me-tering pulses via an indication in-put.The metered values can be dis-played and passed on to a con-trol center as an accumulationwith reset. A distinction is madebetween forward, reverse, activeand reactive energy.

Measuring transducers

n Characteristic with kneeFor measuring transducers itsometimes makes sense to ex-tend a small range of the inputvalue, e.g. for the frequencythat is only relevant in therange 45 to 55, 55 to 65 Hz.This can be achieved by using aknee characteristic.

Functions

n Control and automaticfunctions

Control

In addition to the protectionfunctions, the SIPRORTEC 4units also support all controland monitoring functions thatare required for operatingmedium-voltage or high-voltage substations.The main application is reli-able control of switching andother processes.The status of primary equip-ment or auxiliary devices canbe obtained from auxiliarycontacts and communicatedto the 7SJ62/63 via binary in-puts. Therefore it is possibleto detect and indicate boththe OPEN and CLOSED posi-tion or a fault or intermediatecircuit-breaker or auxiliarycontact position.The switchgear or circuit-breaker can be controlled via:− integrated operator panel− binary inputs− substation control and pro-

tection system− DIGSI 4

Automation

With integrated logic, theuser can set, via a graphic in-terface (CFC), specific func-tions for the automation ofswitchgear or substation.Functions are activated viafunction keys, binary input orvia communication interface.

Switching authority

Switching authority is deter-mined according to parame-ters, communication or bykey-operated switch (whenavailable).If a source is set to“LOCAL”, only local switch-ing operations are possible.The following sequence ofswitching authority is laiddown: “LOCAL”; DIGSI PCprogram, “REMOTE”Every switching operationand change of breaker posi-tion is kept in the status indi-cation memory. The switchcommand source, switchingdevice, cause (i.e. spontane-ous change or command)and result of a switching op-eration are retained.

Key-operated switch

7SJ63/6MD63 units are fittedwith key-operated switchfunction for local/remotechangeover and changeoverbetween interlocked switch-ing and test operation.

Command processing

All the functionality of com-mand processing is offered.This includes the processingof single and double com-mands with or without feed-back, sophisticated monitor-ing of the control hardwareand software, checking ofthe external process, controlactions using functions suchas runtime monitoring andautomatic command termina-tion after output. Here aresome typical applications:n Single and double com-

mands using 1, 1 plus 1common or 2 trip contacts

n User-definable bay inter-locks

n Operating sequences com-bining several switchingoperations such as controlof circuit-breakers, discon-nectors and earthing swit-ches

n Triggering of switching op-erations, indications oralarm by combination withexisting information

Fig. 22

f.tif

Assignment of feedback tocommand

The positions of the circuit-breaker or switching devicesand transformer taps are ac-quired by feedback. These in-dication inputs are logicallyassigned to the correspond-ing command outputs. Theunit can therefore distinguishwhether the indicationchange is a consequence ofswitching operation orwhether it is a spontaneouschange of state (intermediateposition).

Chatter disable

Chatter disable feature evalu-ates whether, in a configuredperiod of time, the number ofstatus changes of indicationinput exceeds a specified fig-ure. If exceeded, the indica-tion input is blocked for a cer-tain period, so that the eventlist will not record excessiveoperations.

Filter time

All binary indications can besubjected to a filter time(indication suppression)

Indication filtering and de-lay

Indications can be filtered ordelayed.Filtering serves to suppressbrief changes in potential atthe indication input. Theindication is passed on only ifthe indication voltage is stillpresent after a set period oftime. In the event of indica-tion delay, there is a wait fora preset time. The informa-tion is passed on only if theindication voltage is still pres-ent after this time.

Indication derivation

A further indication (or acommand) can be derivedfrom an existing indication.Group indications can also beformed. The volume of infor-mation to the system inter-face can thus be reduced andrestricted to the most impor-tant signals.

Transmission lockout

A data transmission lockoutcan be activated, so as toprevent transfer ofinformation to the controlcenter during work on a cir-cuit bay.

Test operation

During commissioning, allindications can be passed toa automatic control systemfor test purposes.



Motor control

For direct activation of thecircuit-breaker, disconnectorand grounding switch operat-ing mechanisms in auto-mated substations, theSIPROTEC 4 units7SJ63/6MD63 with high-performance relays are avail-able.Interlocking of the individualswitching devices takesplace with the aid of pro-grammable logic. Additionalauxiliary relays can be elimi-nated. This results in lesswiring and engineering effort.

Sensitive directionalground-fault detection(ANSI 64, 67Ns)

For isolated-neutral and com-pensated networks, the di-rection of power flow in thezero sequence is calculatedfrom the zero-sequence cur-rent I0 and zero-sequencevoltage V0. For networkswith an isolated neutral, thereactive current componentis evaluated; for compen-sated networks the activecurrent component or resid-ual resistive current is evalu-ated. For special networkconditions, e.g. high-resistance grounded net-works with ohmic-capacitiveground fault current or low-resistance grounded net-works with ohmic-inductivecurrent, the tripping

characteristics can be rotatedapproximately ±45 degrees(see Fig. 45).Two modes of ground faultdirection detection can beimplemented: tripping or in“signaling only mode”.It has the followingfunctions:TRIP via the displacementvoltage V0Two instantaneous elementsor one instantaneous plusone user-defined characteris-tic. Each element can be setin the forward, reverse, ornon-directional.

Directional time-overcurrent protection(ANSI 67, 67N)

Phase and grounddirectionality is performedindependently in the7SJ62/7SJ63. The phase andground function parallel thenon-directional overcurrentelement. Their responsevalue and delay times can beset separately. As an option,inverse directional time-overcurrent protection char-acteristics (IDMTL) can beconnected. The tripping char-acteristic can be rotatedabout ±45 degrees.

The directional overcurrent-time protection maintains avoltage memory of 2 cyclesprior to the fault. By meansof voltage memory,directionality can bedetermined reliably even forclose in (local) faults. If theswitching device closes ontoa fault and the voltage is toolow to determine direction,directionality (directional de-cision) is made with voltagefrom voltage memory. If novoltage exists in memory,tripping occurs according tothe coordination schedule.

Sensitive ground-fault de-tection (ANSI 50N, 51N)

For high-resistance groundednetworks, a sensitive inputtransformer is connected to aphase-balance neutral currenttransformer.

The ground-fault current isalso calculated from thephase currents so that theground fault protectionoperates correctly in theevent of current transformersaturation.

Directional comparisonprotection (cross-coupling)

It is used for selectiveprotection of sections fedfrom two sources withinstantaneous tripping, i.e.without the disadvantage oftime coordination. Thedirectional comparisonprotection is suitable if thedistances between theprotection stations are notsignificant and pilot wires areavailable for signaltransmission. In addition tothe directional comparisonprotection, the directionalcoordinated time-overcurrentprotection is used forcomplete selective back-upprotection. If operated in aclosed-circuit connection, aninterruption of thetransmission line is detected.

Directional comparison protection

Breaker failure protection(ANSI 50BF)

If a faulted portion of theelectrical circuit is not discon-nected upon issuance of atrip command, another com-mand can be initiated usingthe breaker failure protectionwhich operates the circuit-breaker, say, of an upstream(higher-level) protection re-lay. Breaker failure is de-tected if after a trip com-mand, current is still flowingin the faulted circuit. As anoption it is possible to makeuse of the circuit-breaker po-sition indication.

Phase balance current pro-tection (Negative sequenceprotection) (ANSI 46)

In line protection, the two-element phase balance cur-rent/negative sequence pro-tection permits detection onthe high side high-resistancephase-to-phase faults andphase-to-ground faults thatare on the low side of atransformer (e.g., with theswitch group Dy 5). This pro-vides back-up protection forhigh-resistance faults beyondthe transformer. To detectthe unbalanced load, the rationegative-sequence current /nominal current is evaluated.

Auto-reclose (ANSI 79)

Multiple recloses can be de-fined by the user and lockoutwill occur if a fault is presentafter the last reclose. The fol-lowing functions are possi-ble:n 3-phase ARC for all types of

Thermal overload protec-tion (ANSI 49)

For protecting cables andtransformers, an overloadprotection with an integratedprewarning element fortemperature and current canbe applied. The temperatureis calculated using a thermalhomogeneous-body model(according to IEC 60255-8),which takes account both ofthe energy entering theequipment and the energylosses. The calculated tem-perature is constantly ad-justed accordingly. This takesaccount of the previous loadand the load fluctuations.For thermal protection of mo-tors (especially the stator) afurther time constant τ can beset so that the thermal ratioscan be detected correctlywhile the motor is rotatingand when it is stopped. Themodel automatically functionscorrectly, if the equipment isoperated within the limits ofthe ambient temperature forwhich the maximum load cur-rent is rated by the manufac-turer. If the ambient tempera-ture fluctuates (e.g. sum-mer/winter), correction is pos-sible via a second parameterset.The tripping time t iscalculated for a current stepwith static current values acc.to the following form:Overload protection withoutpreload detection

Starting time supervision (ANSI 48)

Starting time supervision protects themotor against long unwanted start-ups,that might occur when excessive loadtorque occurs, excessive voltage dropsoccur within the motor or if the rotor islocked.

flowingIf the trip time is rated according to theabove formula, even a prolonged startupand reduced voltage (and reducedstartup current) will be evaluated cor-rectly.A binary signal is set by a speed sensorto detect a blocked rotor. An instanta-neous tripping is effected. The trippingtime is inverse (current dependent).

Phase balance current protection(ANSI 46)

The negative sequence / phase balancecurrent protection detects a phasefailure or load unbalance due to networkasymmetry and protects the rotor fromimpermissible temperature rise. Todetect the unbalanced load, the ratio ofnegative-sequence current to ratedcurrent is evaluated.

Start inhibit (ANSI 66/86)

If a motor is started up too many timesin succession, the rotor can be subjectto thermal overload, especially the up-per edges of the bars. The rotor temper-ature is calculated from the stator cur-rent and the temperature characteristicis shown in a schematic diagram. Thereclosing lockout only permits startup ofthe motor if the rotor has sufficient ther-mal reserves for a complete startup, seeFig. 50.

Emergency startup

This function disables the reclosing lock-out via a binary input by storing the stateof the thermal image until the binary in-put is active. It is also possible to resetthe thermal replica to zero.

Overvoltage protection(ANSI 59)

The overvoltage protectiondetects unwanted networkand machine overvoltageconditions.

Undervoltage protection(ANSI 27)

The two-element undervolt-age protection provides pro-tection against dangerousvoltage drops (especially forelectric machines). Applica-tions include the isolation ofgenerators or motors fromthe network to avoid unde-sired operating states and apossible loss of stability.Proper operating conditionsof electrical machines arebest evaluated with the posi-tive sequence quantities. Theprotection function is activeover a wide frequency range(45 to 55, 55 to 65 Hz). Theundervoltage protection issupervised by a binary inputusing the CB position toblock protection trips prior toplacing equipment on-line.

Frequency protection(ANSI 81O/U)

Frequency protection can beused for overfrequency andunderfrequency protection.Electric machines and partsof the system are protectedfrom unwanted speed devia-tions. Unwanted frequencychanges in the network canbe detected and the load canbe removed at a specifiedfrequency setting. Frequencyprotection can be used overa wide frequency range (45to 55, 55 to 65 Hz). Four ele-ments (selectable as overfre-quency or underfrequency)and each element can be de-layed separately. Blocking ofthe frequency protection canbe performed if using a bi-nary input or by using anundervoltage element.

Additional functions, whichare not time critical, can beimplemented via the CFC us-ing measured values. Typicalfunctions include reservepower, voltage controlledovercurrent, phase angle de-tection, and zero sequencevoltage detection.

Fault locator

The fault locator specifies thedistance to a fault location inkilometers or miles or thereactance of a second faultoperation.

Inrush restraint

The relay features secondharmonic restraint. If the sec-ond harmonic is detectedduring transformerenergization, triggering of tripnon-directional and direc-tional elements are blocked.

Commissioning

Commissioning could hardlybe easier and is fully sup-ported by DIGSI 4. The sta-tus of the binary inputs canbe read individually and thestate of the binary outputscan be set individually. Theoperation of switching ele-ments (CBs, disconnect de-vices) can be checked usingthe switching functions ofthe bay controller. The analogmeasured values are repre-sented as wide-ranging oper-ational measured values.To prevent transmission ofinformation to the controlcenter during maintenance,the bay controller communi-cations can be disabled toprevent unnecessary datafrom being transmitted.During commissioning, all in-dications with test markingfor test purposes can be con-nected to a control and pro-tection system.

Line feeder with loadshedding

In unstable networks (e.g. sol-itary networks, emergencypower supply in hospitals), itmay be necessary to isolateselected loads from the net-work to prevent overload ofthe overall network. Theovercurrent time protectionfunctions are effective only inthe case of a short circuit.Overloading of the generatorcan be measured as a fre-quency or voltage drop.

Dynamic setting (activated via binary input)

Typical applications

Dynamic setting for cold-load starts

The initiation thresholds andthe tripping times can bechanged for directional andnon-directional time overcur-rent protection functions viabinary input or time control.Example: Cold load pickup af-ter a ten-minute powerfailure.After long outage periods,there is an increased demandfor energy for a limited perioddue to cooling or heating sys-tems. The less sensitive set-tings are activated with theaid of a timer (CB OPENtime). When a second timer(ACTIVE time) finishes itsrun, the original settings arereactivated.A third timer (STOP time) su-pervises the process, startingas soon as the current levelfalls below the original set-ting. If the current stays be-low that level while the se-cond timer is running, theoriginal setting is reactivatedafter the third timer finishesist run. This gives more reli-ability on protection, sincethe original settings are reac-tivated faster.

Protection on connectingto a short-circuit

If connection is switchedonto a fault, instantaneoustripping can be effected. Ifthe internal control functionis used (local, via binary inputor via serial interface), themanual closing function isavailable without any addi-tional wiring. If the feeder isconnected via an externalcircuit-breaker bypassing theinternal control function,manual detection using a bi-nary input is implemented.

Auto-reclose

The auto-reclose featuresprovide starting and blockingfunctions as described onpage 20. Figure 63 gives anexample where the blockingof the reclosing function isapplied. Time current coordi-nation is implemented withthe time-overcurrent settingsof the bay controller. If a faultoccurs, the feeder is trippedwith an instantaneous ele-ment and automaticallyreclosed. With the circuit-breaker operating instanta-neously, no other protectiondevices will operate (fusesaving scheme). If the faultstill exists after the breaker isautomatically reclosed, addi-tional reclosing attempts canbe made. (A high-set instan-taneous element of the up-stream breaker can be set soit will not operate for a faultbeyond the downstream pro-tection device.) Low-set in-stantaneous elements of theupstream breaker will beblocked during subsequentfaults on the feeder; how-ever, the downstreambreaker can be set to providean additional instantaneoustrip or be time-delayed to al-low downstream fuses to op-erate. If sufficient time delayis provided, a downstreamfuse can operate and no fur-ther breaker operations arerequired. Time coordinationof the breakers will limit theoutage to a smaller portion ofthe feeder if the fault isdownstream of the secondbreaker. If additionalreclosing equipment is in-stalled on the same feeder,




Transformer protection

The high-set element permitscurrent coordination where theovercurrent element functionsas a back-up for the lower-levelprotection relays, and the over-load function protects the trans-former from thermal overload.Low-current single-phase faultson the low voltage side that mapinto the negative-sequence sys-tem on the high-voltage side canbe detected with the negativesequence protection. The avail-able inrush restraint preventstripping due to inrush currentsof the transformer.

Fig. 65

Typical protection of a transformer

Fig. 64

Bus protection (reverse interlocking)

reclosing schemes canbe altered to limit protec-tion to smaller portions ofthe feeder (zone se-quencing). Relay settingsare assigned and allowthe furthest downstreambreaker to operate first.This makes it possible toreduce the number ofreclosing attempts on thefeeder.

Busbar protection(reverse interlocking)

By using binary inputs(closed-circuit oropen-circuit current) it ispossible to block the highcurrent tripping of individ-ual protection relays. Inthis way, it is possible toimplement a simple busprotection (reverse inter-lock scheme).

Typical protection of a high-voltageasynchronous motor

Motor protection

For short-circuit protection, e.g.elements 50 and 50N are avail-able. The stator is protectedagainst thermal overload by 49(υs), the rotor by 46 (I2>), start-ing time supervision (48) andstart inhibit (66/68). Via a binaryinput, it is possible to detect alocked rotor and isolate imme-diately. The reclosing lockoutcan be deactivated for “emer-gency startup”.The undervoltage functionprevents startup on insufficientvoltage and the overvoltagefunction prevents insulationdamage.

The product complies with the provisions of the directive of the Council of theEuropean Union for harmonization of the legislation of the member states aboutelectro-magnetic compatibility (EMC directive 89/336/EEC). The product complies withthe international standard of the IEC 60255 series and the German national standardDIN VDE 57 435/Part 303.

The tests made by Siemens EV S show no indications of any problems of theyear 2000 compliance for the relays. Neither the performance nor the functionalityof the protection relays become negatively affected through input of a date,which will be before, during or after the year 2000. The tests were made according tothe recognized rules of the British Standards Institute (BSI).Because of the complexity of the application, a residual risk regarding the date functionmay not be totally excluded.
