ABB REF610 is a feeder protection device,which is a member of the 615 product series in the ABB Relion®product family.The following is a detailed introduction to ABB REF610:

1.Product Overview

As a feeder device,REF610 is mainly used to protect,measure and monitor public and industrial distribution systems.Its plug-in design facilitates the commissioning of switchgear and makes the insertion and removal of protection device plug-ins faster and safer.

2.Main features

Multi-function protection:

REF610 provides comprehensive protection functions,including three-phase non-directional overcurrent protection(with timing or IDMT characteristics,low setting stage,high setting stage and instantaneous level),non-directional ground fault protection(with timing or IDMT characteristics,low setting stage and high setting stage),phase discontinuity protection,three-phase cable thermal overload protection,etc.

In addition,REF610 also provides an optional arc protection function for detecting arc conditions in air-insulated metal armored switchgear and providing fast substation busbar arc fault protection.

Human Machine Interface:

The REF610 is equipped with a liquid crystal display(LCD)and navigation buttons,making local use of the relay safe and easy.

The user can control the relay locally through serial communication via a computer connected to the front communication port.At the same time,remote control can be achieved through the rear connector connected to the control and monitoring system via the serial communication bus.

Communication and expansion:

The REF610 supports a variety of communication protocols,such as SPA bus,IEC 60870-5-103 or Modbus(RTU and ASCII),which facilitates data exchange and integration with other devices and systems.

Optional rear communication modules provide more communication options,such as plastic fiber,combined fiber(plastic and glass)or RS-485 connection.

Wide range of applications:

The REF610 is mainly used to protect incoming and outgoing lines in distribution substations for resistance-grounded and solidly grounded power systems.

It is also suitable for marine and offshore environments and offers a compact body design and a removable plug-in design,making daily maintenance quick and simple.

Self-monitoring and fault recording:

REF610 has a self-monitoring system that continuously monitors the operation of the relay.

It is also equipped with a fault recording module that can record event data for up to 80 seconds,including four analog channels and up to eight user-selectable digital channels.

III.Application Areas

REF610 has a wide range of applications in public power distribution and industrial applications,and can be used as a dedicated protection relay.In addition,in industrial applications and power distribution networks,it can also be used as backup protection for motors,transformers and generators.
