ABB RET615 ANSI Transformer Protection and Control Overview

Overview

RET615 is a dedicated transformer protection and control relay for power transformers,

unit and step-up transformers including power generator-transformer blocks in utility and

industry power distribution systems. RET615 is a member of ABB’s Relion® product

family and part of its 615 protection and control product series. 

The 615 series relays are characterized by their compactness and withdrawable-unit design.

Re-engineered from the ground up, the 615 series has been designed to unleash the full

potential of the IEC 61850 standard for communication and interoperability between

substation automation devices. Once the standard configuration relay has been given the

application-specific settings, it can directly be put into service.

The 615 series relays support a range of communication protocols including IEC 61850

with Edition 2 support, process bus according to IEC 61850-9-2 LE, Modbus® and DNP3.

The IEC 61850 communication implementation supports all monitoring and control

functions. Additionally, parameter setting and DFR records can be accessed using the IEC

61850 protocol. Oscillographic files are available to any Ethernet-based application in the

standard COMTRADE format. The protection relay can send and receive binary signals

from other devices (so-called horizontal communication) using the IEC 61850-8-1

GOOSE profile, where the highest performance class with a total transmission time of 3

ms is supported. Furthermore, the protection relay supports sending and receiving of

analog values using GOOSE messaging. The protection relay meets the GOOSE

performance requirements for tripping applications in distribution substations, as defined

by the IEC 61850 standard. The protection relay can simultaneously report events to five

different clients on the station bus.

The protection relay can support five simultaneous clients. 

If PCM600 reserves one client connection, only four client connections are left, for example, for IEC 61850 and Modbus.

All communication connectors, except for the front port connector, are placed on

integrated optional communication modules. 

The protection relay can be connected to Ethernet-based communication systems via the 

RJ-45 connector (100Base-TX) or the fiber optic LC connector (100Base-FX).
