Preface

NOTE

indicates information on the device, handling of the device, or the respective part of the instruction manual
which is important to be noted.

WARNING

Qualified Personnel

Commissioning and operation of the equipment (module, device) as set out in this manual may only be
carried out by qualified personnel. Qualified personnel in terms of the technical safety information as set
out in this manual are persons who are authorized to commission, activate, to ground and to designate
devices, systems and electrical circuits in accordance with the safety standards.

Use as prescribed

The operational equipment (device, module) may only be used for such applications as set out in the cata­logue and the technical description, and only in combination with third-party equipment recommended or
approved by Siemens.

The successful and safe operation of the device is dependent on proper handling, storage, installation,
operation, and maintenance.

When operating an electrical equipment, certain parts of the device are inevitably subject to dangerous
voltage. Severe personal injury or property damage may result if the device is not handled properly.

Before any connections are made, the device must be grounded to the ground terminal.
All circuit components connected to the voltage supply may be subject to dangerous voltage.
Dangerous voltage may be present in the device even after the power supply voltage has been removed

(capacitors can still be charged).
Operational equipment with open circuited current transformer circuits may not be operated.
The limit values as specified in this manual or in the operating instructions may not be exceeded. This

aspect must also be observed during testing and commissioning.

Typographic and Symbol Conventions

The following text formats are used when literal information from the device or to the device appear in the
text flow:

Parameter Names

Designators of configuration or function parameters which may appear word-for-word in the display of the
device or on the screen of a personal computer (with operation software DIGSI), are marked in bold letters in
monospace type style. The same applies to titles of menus.

1234A

Parameter addresses have the same character style as parameter names. Parameter addresses contain the
suffix A in the overview tables if the parameter can only be set in DIGSI via the option Display additional
settings.

Parameter Options

Possible settings of text parameters, which may appear word-for-word in the display of the device or on the
screen of a personal computer (with operation software DIGSI), are additionally written in italics. The same
applies to the options of the menus.

Indications

Designators for information, which may be output by the relay or required from other devices or from the
switch gear, are marked in a monospace type style in quotation marks.

Deviations may be permitted in drawings and tables when the type of designator can be obviously derived
from the illustration.

The following symbols are used in drawings:

Introduction

1.1 Overall Operation

1.1

Analog Inputs

Overall Operation

The numerical, multi-functional protection device SIPROTEC 7SJ61 is equipped with a powerful microproc­essor. It allows all tasks to be processed digitally, from the acquisition of measured quantities to sending
commands to circuit breakers. Figure 1-1 shows the basic structure of the device.

The measuring inputs (MI) convert the currents coming from the instrument transformers and adapt them to
the level appropriate for the internal processing of the device. The device has 4 current inputs. three of these
are for the input of the phase currents. Depending on the model, the fourth current input (ΙN) may be used for

measuring the ground fault current ΙN (current transformer starpoint) or for a separate ground current trans­former (for ground fault detection ΙNs). The analog input quantities are passed on to the input amplifiers (IA).

[hw-struktur-7sj61-020702-kn, 1, en_US]

Figure 1-1

The input amplifier IA stage provides a high-resistance termination for the input quantities. It consists of filters
that are optimized for measured-value processing with regard to bandwidth and processing speed.

The analog-to-digital (AD) element consists of a multiplexor, an analog-to-digital (A/D) converter and of
memory components for the transmission of digital signals to the microcomputer system.

Microcomputer System

Apart from processing the measured values, the microcomputer system (μC) also executes the actual protec­tion and control functions. They especially include:

Filtering and preparation of the measured quantities

•

Continuous monitoring of the measured quantities

•

Monitoring of the pickup conditions for the individual protective functions

•

Interrogation of limit values and sequences in time

•

Control of signals for the logic functions

•

Output of control commands for switching devices

•

Recording of messages, fault data and fault values for analysis

•

Management of the operating system and the associated functions such as data recording, real-time

•

clock, communication, interfaces, etc.

The information is distributed via output amplifiers (OA).

•

Binary Inputs and Outputs

The computer system obtains external information through the binary input/output boards (inputs and
outputs). The computer system obtains information from the system (e.g remote resetting) or from external
equipment (e.g. blocking commands). These outputs include, in particular, trip commands to circuit breakers
and signals for the remote indication of important events and conditions.

Front Panel

Introduction

1.1 Overall Operation

Optical indicators (LEDs) and a front display panel (LC display) provide information on the function of the
device, and indicate events, states and measured values.

Integrated control and numeric keys in conjunction with the LCD enable interaction with the remote device.
These elements can be used to access the device for information such as configuration and setting parame­ters. Similarly, setting parameters can be accessed and changed if needed.

In addition, control of circuit breakers and other equipment is possible from the front panel of the device.

Serial Interfaces

The Front PC Interface is provided for local communications with a personal computer using the DIGSI soft­ware. This facilitates a comfortable handling of all device functions.

The Rear Service Interface can also be used to communicate with the relay from a PC running the DIGSI soft­ware. This interface is especially well suited for a permanent connection of the devices to the PC or for opera­tion via a modem. The service interface can also be used to connect an RTD box (= resistance temperature
detector) for obtaining external temperatures (e.g. for overload protection).

All data can be transferred to a central control center or monitoring system via the serial System Interface.
This interface may be provided with various protocols and physical transmission schemes to suit the particular
application.

A further interface is provided for the time synchronization of the internal clock via external synchronization
sources.

A range of communication protocols are available from a variety of additional interface modules.
The operator or service interface allows you to operate the device from a remote location or on site using a

standard browser. This is possible during commissioning, checking and also during operation of the devices.
The SIPROTEC 4 Standard “WEBMonitor” is available for this task.

Power Supply

A power supply unit (Vaux or PS) delivers power to the functional units using the different voltage levels.
Voltage dips may occur if the voltage supply system (substation battery) becomes short-circuited. Usually,
they are bridged by a capacitor (see also Technical Data).

Introduction

1.2 Application Scope

1.2

Protective Functions

Application Scope

The numerical, multi-functional SIPROTEC 4 7SJ61 is a versatile device designed for protection, control and
monitoring of busbar feeders. For line protection, the device can be used in networks with earthed, low resist­ance earthed, isolated or compensated neutral point. It is suited for networks that are radial and supplied from
a single source or open looped networks. The device is equipped with motor protection applicable for asyn­chronous machines of all sizes.

The device includes the functions that are necessary for protection, for monitoring of circuit breaker positions,
and control of the circuit breakers in straight bus applications or breaker-and-a-half configurations; therefore,
the devices can be universally employed. The devices also provide excellent backup facilities of differential
protective schemes of lines, transformers, generators, motors, and busbars of all voltage levels.

Non-directional overcurrent protection (50, 50N, 51, 51N) is the basis of the device. There are three definite
time overcurrent protective elements and one inverse time element for the phase currents and the ground
current. For inverse time overcurrent protective elements, several curves of different standards are provided.
Alternatively, user-defined characteristic can be programmed.

Depending on the variant ordered, the overcurrent time protection can feature breaker failure protection and
ground fault protection for high-resistence ground short-circuits and faults.

In addition to the fault protection functions already mentioned, other protective functions are available. Some
of them depend on the version of the device that is ordered. These additional functions include negative
sequence protection (46), thermal overload protection (49) with start inhibit for motors (66/68), and motor
starting protection (48), as well as automatic reclosing (79) which allows different reclosing cycles on over­head lines. An automatic reclosing system may also be connected externally.

A protection feature can be ordered for the detection of intermittent ground faults which detects and accumu­lates transient ground faults.

External detectors account for ambient temperatures or coolant temperatures (by means of an external
RTDbox).

Control Functions

The device features a control function for activating and deactivating switchgears via the integrated operator
panel, the system interface, binary inputs, and the serial port using a personal computer with DIGSI.

The status of the primary equipment can be transmitted to the device via auxiliary contacts connected to
binary inputs. The present status (or position) of the primary equipment can be displayed on the device, and
used for interlocking or alarm condition monitoring. The number of operating equipments to be switched is
limited by the binary inputs and outputs available in the device or the binary inputs and outputs allocated for
the switch position indications. Depending on the primary equipment being controlled, one binary input
(single point indication) or two binary inputs (double point indication) may be used for this process.

The capability of switching primary equipment can be restricted by a setting associated with switching
authority (Remote or Local), and by the operating mode (interlocked/non-interlocked, with or without pass­word request).

Processing of interlocking conditions for switching (e.g. switchgear interlocking) can be established with the
aid of integrated, user-configurable logic functions.

Messages and Measured Values; Recording of Event and Fault Data

The operational indications provide information about conditions in the power system and the device. Meas­urement quantities and values that are calculated can be displayed locally and communicated via the serial
interfaces.

Device messages can be assigned to a number of LEDs on the front cover (allocatable), can be externally
processed via output contacts (allocatable), linked with user-definable logic functions and/or issued via serial
interfaces.

During a fault (system fault) important events and changes in conditions are saved in fault protocols (Event
Log or Trip Log). Instantaneous fault values are also saved in the device and may be analyzed subsequently.

C53000-G1140-C210-6, Edition 05.2016

Communication

The following interfaces are available for the communication with external operating, control and memory
systems.

A 9-pole DSUB miniature female connector on the front panel serves the purpose of local communication with
a PC. By means of the SIPROTEC 4 operating software DIGSI, all operational and evaluation tasks can be
executed via this operator interface, such as specifying and modifying configuration parameters and settings,
configuring user-specific logic functions, retrieving operational messages and measured values, inquiring
device conditions and measured values, issuing control commands.

Depending on the individual ordering variant, additional interfaces are located at the rear side of the device.
They serve to establish extensive communication with other digital operating, control and memory compo­nents.

The service interface can be operated via electrical data lines or fiber optics and also allows communication
via modem. For this reason, remote operation is possible via personal computer and the DIGSI operating soft­ware, e.g. to operate several devices via a central PC.

The system interface ensures the central communication between the device and the substation controller. It
can also be operated via data lines or fibre optic cables. Standard protocols are available to transmit data
according to IEC 60870-5-103 via system port. The integration of the devices into the automation systems
SINAUT LSA and SICAM can also take place with this profile.

An EN 100 module allows integrating the devices into 100-Mbit Ethernet communication networks of the
process control and automation system using IEC 61850, PROFINET or DNP 3.0 TCP protocols. Besides the link
with the process control and automation system, this interface also processes DIGSI communication, interrelay
communication via GOOSE and connection of a SICAM I/O unit.

Alternatively, field bus coupling with PROFIBUS FMS is available for SIPROTEC 4. The PROFIBUS FMS according
to DIN 19245 is an open communication standard that particularly has wide acceptance in process control and
automation engineering, with exceptional high performance. A profile has been defined for the PROFIBUS
communication that covers all of the information types required for protection and process control engi­neering. The integration of the devices into the power automation system SICAM can also take place with this
profile.

Besides the field-bus connection with PROFIBUS FMS, further coupling options are possible with PROFIBUS DP
and the protocols DNP 3.0 and MODBUS. These protocols do not support all possibilities which are offered by
PROFIBUS FMS.

Furthermore, a redundant IEC 60870-5-103 interface is available.

Setting the Functional Scope

General

The settings associated with the various device functions can be modified using the operating or service inter­face in DIGSI in conjunction with a personal computer. Some parameters can also be changed using the
controls on the front panel of the device. The procedure is described in detail in the SIPROTEC System Descrip­tion /1/ SIPROTEC 4 Systembeschreibung.

Functional Scope

The 7SJ61 relay contains protection functions as well as auxiliary functions. The hardware and firmware is
designed for this scope of functions. Additionally, the control functions can be matched to the system require­ments. Individual functions can be enabled or disabled during the configuration procedure. The interaction of
functions may also be modified.

Description

Example for the configuration of the functional scope:
A protected system consists of overhead lines and underground cables. Since automatic reclosing is only

needed for the overhead lines, the automatic reclosing function is not configured or “disabled” for the relays
protecting the underground cables.

The available protection and additional functions can be configured as Enabled or Disabled. For individual
functions, a choice between several alternatives may be possible, as described below.

Functions configured as Disabled are not processed by the 7SJ61. There are no messages and corresponding
settings (functions, limit values) queried during configuration.

NOTE

Available functions and default settings are depending on the order variant of the relay (see A Ordering

Information and Accessories).

2.1.1.2

Setting the Functional Scope

Special Features

Setting Notes

Configuration settings can be entered using a PC and the software program DIGSI and transferred via the front
serial port or the rear service interface of the device. The operation via DIGSI is explained in the SIPROTEC 4
System Description.

For changing configuration parameters in the device, password no.7 is required (for parameter set). Without
the password, the settings can be read but not modified and transmitted to the device.

The functional scope with the available options is set in the Functional Scope dialog box to match plant
requirements.

Most settings are self-explanatory. The special features are described below.
If you want to use the setting group change function, set address 103 Grp Chge OPTION to Enabled.

Simple and fast changeover between up to four different setting groups is possible in service. Only one setting
group can be selected and used if this option is Disabled.

For the overcurrent elements of the time overcurrent protection (separately for phase currents and ground
current), various tripping characteristics can be selected at address 112 Charac. Phase and 113 Charac.
Ground. If only the definite characteristic is desired, then Definite Time should be selected. Additionally,
depending on the version ordered, various inverse time characteristic, based on either IEC (TOC IEC) stand­ards or ANSI (TOC ANSI standards), or user-defined characteristic are available for selection. The dropout
behaviour of the IEC and ANSI characteristic will be specified later with settings (addresses 1210 and 1310).

2.1 General

But for the user-defined characteristic, you can choose in address 112 and 113 whether to specify only the
pickup characteristic (User Defined PU) or the pickup and the dropout characteristic (User def.
Reset).

Additionally, the superimposed high-current elements 50-2 and 50-3 are available in all these cases. Time
overcurrent protection may be set to Disabled during configuration.

For (sensitive) ground fault detection, address 131Sens. Gnd Fault is used to specify whether this func­tion is enabled with a definite time (Definite Time) characteristic, inverse time characteristics TOC IEC or
TOC ANSI, one User Defined PU and two logarithmic inverse characteristics, or the entire function is set
to Disabled.

For the intermittent ground fault protection, you can specify the measured quantity (with Ignd, with 3I0
or with Ignd,sens.) to be used by this protection function at address 133 INTERM.EF.

For negative sequence current protection, address 140 46 is used to specify whether the tripping characteris­tics should be Definite Time or TOC ANSI or TOC IEC, or whether the function is to be Disabled.

For overload protection, address 142 49 allows you to specify whether the thermal replica of the overload
protection will account for a coolant temperature or ambient temperature (With amb. temp.) or not (No
ambient temp), or whether the entire function is Disabled.

For the circuit-breaker maintenance function, several options are available under address 172 52 B.WEAR
MONIT Irrespective of this, the basic functionality of the summation current formation (ΣΙ procedure) is always
active. It requires no further configurations and adds up the tripping currents of the trips initiated by the
protection functions.

When selecting the ΣIx-procedure, the sum of all tripping current powers is formed and issued as a reference
value. The 2P procedure continuously calculates the remaining lifespan of the circuit breaker.

With theΙ2t-procedure, the square fault current integrals are formed via arc time and are issued as a reference
value.

For more detailed information about the circuit breaker maintenance procedures, see Section 2.17.2 Statistics.
When using trip circuit supervision, address 182 74 Trip Ct Supv allows you to select whether this func-

tion should work with two (2 Binary Inputs) or only one binary input (1 Binary Input) or if the func­tion is Disabled.

If you want to detect an ambient temperature or a coolant temperature and send the information e.g. to the
overload protection, specify the port to which the RTD-box is connected in address 190 RTD-BOX INPUT. For
7SJ61 the port C (service port) is used for this purpose. The number and transmission type of the temperature
detectors (RTD = Resistance Temperature Detector) can be specified in address 191 RTD CONNECTION: 6 RTD
simplex or 6 RTD HDX (with one RTD-box) or 12 RTD HDX (with two RTD-boxes). Implementation exam­ples are given in the Appendix (under "Connection Examples"). The setings in address 191 have to t comply
with those at the RTD-box (see Section 2.14.2 Setting Notes, “RTD-box”).

The flexible protection functions can be configured via the FLEXIBLE FUNC. parameter. Up to 20 functions
can be created. This is done by setting checkmarks at the functions. If the checkmark of a function is removed,
all settings and configurations made previously will be lost. After re-selecting the function, all settings and
configurations are in default setting. Setting of the flexible function is done in DIGSI under “Parameters”,
“Additional Functions” and “Settings”“. The configuration is done as usual under “Parameters” and “Configura­tion”.
