ABB REV615 Capacitor bank protection and control REV615

The 610 series protection relays are suitable for employment in marine and offshore environments.

The numerical voltage protection relays of the 610 series support a wide range of standard communication protocols,

among them the IEC 61850, IEC 60870-5-103, DNP3, Modbus,Profibus, LON and SPA communication protocols.

The REM 545 machine terminals are used as the main protection system of generator and generator-transformer 

units in small and medium-power diesel, hydroelectric and steam power plants. 

The protection for large and/or important MV synchronous and asynchronous motors used, 

for example, in pumps, mills and crushers during start-up and normal run forms another application area.

The protection functions of REM 545 are designed for selective short-circuit and earth-fault protection of rotating machines. 

Unlike most other power system components, rotating machines also need protection against abnormal 

operating conditions such as over-current, unbalanced load, over-temperature, over-voltage, over and under-excitation, 

under-impedance, over- and under-frequency and generator motoring. 

For motor protection start-up supervision, there are also stall protection and cumulative start-up counter features.

Description

REU610 is a voltage protection relay for system voltage protection, 

measuring and supervising in utility and industrial power systems.

REU610 is a member of ABB’s Relion® protection and control product family and part of its 610 product series. 

The 610 series includes protection relays for feeder protection, motor protection and general system voltage supervision. 

The plug-in design of the 610 series protection relays facilitates the commissioning of the switchgear and

enables fast and safe insertion and withdrawal of relay plug-in units.

The protection relay is primarily designed for the overvoltage protection of power system components, such as busbars,

feeders, power transformers and capacitor batteries. 

It is also used for the general power system earth-fault supervision.

Further, the protection relay can be used for undervoltage protection of motors and overvoltage protection of capacitor

batteries, for initialization of automatic busbar changeover and disconnecting small power units from the network in case of a major network disturbance.
