Why reverse power relay is used?

Answer Posted / sudheer

if two generators synchronised and are punning parallel,
the total load divided and generator takes half of the
total load upon it.
some times because of load unbalancing one generator
shifts his total load on second generator and run as a
motor . before this condition the generator is taking load
upon him and now it will became as a load and it will run
as a motor insted of generator.
in this condition the second generator winding can be
damage, so we use reverse power relay. because the
direction changed of power , so we called it reverse
power .
