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.
The relay can be used for 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.
