The Reverse power relay is of Directional Relay.
The function of the Direction Relay is to sense(activate) if
the direction of the power is changed.

Answer / mahendra

Reverse power relay which acts according to the direction
of current flow.
For Example : it is normally used in Generator protection.
because generator produce power ie it gives the current.

when the generator speed reduced, load decreaes to zero
gradually, power will flow into the generator & act as a
motor if the Generator circuit breaker is not opened.

This is sensed by the CT, direction of the flow of current.

which circuit takes max. load & which circuit takes min. load i.e. SERIES CIRCUIT OR PARALLEL CIRCUIT??
