ABB REF615

ABB REF615 is a dedicated feeder protection and measurement and control device.It is a member of the 615 product series in the ABB Relion®product family.The following is a detailed introduction to ABB REF615:

I.Main features and functions

Protection and control:

REF615 is designed for protection,control,measurement and monitoring of public and industrial distribution systems.It is suitable for neutral point non-grounded power grids and neutral point resistance or impedance grounded power grids.

Provides a variety of protection and control functions such as directional overcurrent,non-directional overcurrent,and grounding protection.

High sensitivity and selectivity:

Equipped with highly sensitive and selective grounding fault protection,as well as a combination of multi-frequency admittance grounding protection.

Supports advanced short-circuit and grounding fault location functions.

Communication and integration:

Supports substation IEC61850 communication standards,including parallel redundancy protocol(PRP)and high availability seamless redundancy protocol(HSR).

Also supports communication protocols such as DNP3,IEC 60870-5-103 and Modbus®,which is convenient for integration with other devices and systems.

Display and operation:

Equipped with a large,easy-to-read LCD display,it can be accessed and operated via local or remote HMI.

A pull-out design is provided for easy installation and maintenance.
