Recorded data

The relay can store the records of the latest 128 fault events.

The records can be used to analyze the power system events.

Each record includes, for example, current, voltage and angle

values and a time stamp. The fault recording can be triggered

by the start or the trip signal of a protection block, or by both.

The available measurement modes include DFT, RMS and

peak-to-peak. Fault records store relay measurement values

when any protection function starts. In addition, the maximum

demand current with time stamp is separately recorded. The

records are stored in the nonvolatile memory.

Load profile

The load profile recorder stores the historical load data

captured periodically (demand interval). Up to 12 load

quantities can be selected for recording and storing in the

nonvolatile memory. The recordable quantities include

currents, voltages, power and power factor values. The

recording time depends on a settable demand interval

parameter and the amount of quantities selected. The

quantities’ type and amount to be recorded are determined in

the application configuration. The recorded quantities are

stored in the COMTRADE format.

Event log

To collect sequence-of-events information, the relay has a

nonvolatile memory capable of storing 1024 events with the

associated time stamps. The event log facilitates detailed pre

and post-fault analyses of feeder faults and disturbances. The

considerable capacity to process and store data and events in

the relay supports the growing information demand of future

network configurations.

The sequence-of-events information can be accessed either via

the LHMI or remotely via the communication interface of the

relay. The information can also be accessed locally or remotely

using the Web HMI.

Self-supervision

The relay’s built-in self-supervision system continuously

monitors the state of the relay hardware and the operation of

the relay software. Any fault or malfunction detected is used for

alerting the operator.

A permanent relay fault blocks the protection functions to

prevent incorrect operation.

Key benefits

• Keeps assets productive at the highest levels of safety,

redundancy and availability

• Up to 20 different circuit breakers can be synchronized by

one SYNCHROTACT 6 unit

• All hardware and software is housed in a single unit

• Proven technology and reliable components

• Backwardly compatible with previous SYNCHROTACT

generations for easy and cost-effective retrofits

The number of parameter sets has been increased from 7 to

20. enabling up to 20 different circuit breakers to be

synchronized by a single SYNCHROTRACT 6 device. Compliant

with the IEC 61850 Ed. 2 international communication

standard, SYNCHROTACT 6 fulfills the most demanding

requirements and offers a choice between an electrical or

optical interface.

Diverse dual channel design

SYNCHROTACT 6 is the only synchronizer to have a diverse

dual channel design – if one channel should fail, the other

prevents the circuit breaker from closing under non

synchronous conditions. Both channels are in the same

SYNCHROTACT unit to minimize wiring, ensure perfect

working compatibility and reduce commissioning and

engineering costs.
