Simple yet comprehensive,safe, and reliable

SIPROTEC Compact is the ideal solution for almost every protection application

Perfectly suited for protection in

distribution systems and industry,

with minimal space requirement

SIPROTEC Compact devices provide acomprehensive range of functions in asurprisingly compact and space-savinghousing.

Whether as main or as backup protection,a single SIPROTEC Compact device pro-vides protection functionality for everyconceivable fault. And it can do evenmore it supports the control, automa-tion, and monitoring functions in thesubstation.

Simple to operate and highly flexible

The proven concept behind the SIPROTECCompact range of devices allows effi-cient and safe operation. The devicescan be parameterized completely withthe DIGSI 4 parameterization tool. Thesix-line display and eight LEDs indicateall operating states. The new freely pro-grammable function keys can be inte-grated in the application by the user.With the programmable logic (CFC) and

flexible protection functions the devicecan be adapted to meet the individualrequirements in terms of protection for abroad range of applications. Exchange-able communications interfaces will meetfuture standards, thereby providing secu-rity of investment.

The comprehensive experience of the

market leader in a single deviceThe SIPROTEC Compact range stands forthe cumulative experience of millions ofsuccessfully operating Siemens systems.They are based on the SIPROTEC 4 range,which has been used in countless sys-

tems and applications worldwide to date.Cutting-edge hardware

Pluggable terminal blocks make theinstallation and retrofitting of all voltageand current connections a breeze. Nospecial tools are required, and settingsand adaptations are done via softwareparameters.

Much more than a protection deviceIn addition to protection functions, SIPROTEC Compactdevices also support control, monitoring, and automationprocesses. The comprehensive range of features alongwith communications interfaces ensure that the devicescan be fully integrated in the centralized control, support-ing control, and service communication. In addition, itprovides for connections to be made with other devices,for example via an optical loop according to IEC 61850with other SIPROTEC 4 devices.

Communications interfaces:

Interface:

- IEC 61850

- IEC 60870-5-103- PROFIBUS DP

- DNP 3.0

- MODBUS RTU

Ethernet interface for DIGSI 4 or for optical protectioninterfaces for differential protection

DIGSI 4 is the application software on the users PC for theinterface with SIPROTEC devices providing all the relatedfunctionality. DIGSI 4 is specifically developed for indus-trial and utility applications, making the parameterizationand evaluation of SIPROTEC devices really easy.

The PC software is downward-compatible and provides auser-friendly and intuitive user interface. The interfaceallows tasks to be carried out simply and conveniently,from the parameterization and commissioning of devicesto the analysis and documentation of system distur-bances. A powerful analysis tool supports quick fault-find-ing and also provides important information for mainte-nance cycles.

For a broad range of users, DIGSI 4 has already become an

established name in the business.

DIGSI 4 at a glance:

Mapping of all substation topology types

Import and export of parameter sets

Flexible and intuitive application of user-defined logicwith a logic editor (CFC) no prior programmingknowledge is necessary

Precise fault analysis and visualization using SIGRA

Routing of inputs and outputs with a visually clearmatrix (no dialog boxes)

Intelligent plausibility checks avoid wrong inputs andsettings

SIPROTEC Compact 7SJ81 makes the advantages of low-power current transformers available.

The device provides four low-power current transformerinputs along with the required protection and controlfunctions.

Since low-power current transformers cover a very broadrange of primary nominal current while operating almostwithout saturation, cost-efficient and safe system solu-tions can be created.

Highlights

Savings in terms of spares and logistics because only afew low-power current transformer types cover thecomplete range of conventional transformers while pro-viding protection and measurement CT functionality

High operational safety, since low-power current trans-formers can be operated with short circuit and opencircuit on the secondary side

Minimal device size of the transformer core, making itideal for compact switchgear systems in energy distri-bution and industrial applications

Linear and almost no saturation up to short-circuitcurrent

Reduction of current transformer types thanks to a highdynamic range and a high precision level

In the event of an increase in branch nominal currentthere is no need for replacement of CT thanks to high,linear transmission range

Time-overcurrent protection 7SJ81 forconnecting to low-power current transformers

The SIPROTEC Compact 7RW80 has been designed espe-cially for energy distribution applications, for use on trans-formers, and on electrical machines. It can detect devia-tions from the permitted voltage or frequency andprovides overexcitation protection. The device can also beused for decoupling networks or for load shedding in theevent of hazardous network breakdowns arising as a resultof impermissibly high frequency drops. The integratedload connection function enables the network to berestored automatically, once the required network fre-quency has been reestablished.

The SIPROTEC Compact 7SD80 line differential protectiondevice can be used for the selective protection of lines inmedium-voltage networks with all types of neutral pointgrounding. For protection data exchange the differentialprotection uses the integrated two-wire (twisted pair) andFO interfaces in the device. Therefore the 7SD80 can beadapted to existing fibre-optical or copper communicationlines which makes it future proof for new investments.

The integrated time-overcurrent protection can be direc-tional or non-directional. This allows for the applicationof protection concepts such as reverse interlocking inmeshed networks or emergency mode protection in theevent of communication failure.

The 7SD80 is perfectly tailored to networks with distrib-

uted generation.

Highlights:

Differential protection for all types of network andneutral point grounding

Safe recognition of high and low-resistance faults

Efficient protection concepts with powerful additionalfunctions

Optimal use of the existing infrastructure with differentmedia for protection-data interface

Optional redundant protection-data interface
