Single Phase Reverse Power Relay

MRP11 is micro controller based single phase, reverse power relay with one measuring element. Relay  operates  for  pure  active  reverse  power  only  and will  not  cause  spurious  tripping  due  to  PF  fluctuations  in  the  system. Relay can work as a reverse reactive power relay with an addition potential transformer.

Salient Features

  • 0.5% sensitivity
  • Four Quadrant operations
  • Reactive power option
  • Voltage Input: 110 / 415 V AC (Field Selectable)


The  relay  can  be  used  protection  of  generators  from  reverse  power conditions  or  in  grid  islanding  systems  for  detecting  mains  failure  or  prevention  of  power flow  from  small  generators  to  grid.
