The reverse power relay is used to monitor the direction of
power from A.C generators, if the current in the system
being monitored is reversed, to a value greater than the
customer adjustable preset limit the relay will energise.
The adjustable trip point is 2% to 20% of input current. An
adjustable time delay of 0 to 20 seconds is provided.
Correct setting of the trip point and time delay, will
ensure protection against motoring action of the Syn gen.

An inadverdent relay is used to trip the circuit when a syn
gen has been energised or excited inadvertently.
