Several types of Reverse Power Relays are available
including relays sensitive to reverse reactive power
(KVAR). WILMAR is the leading brand of reverse power
relays. Our rugged sealed construction provides con-
tinuous and reliable operation unaffected by shock,
vibration or other severe environments. Reverse Power
Relays are used for the protection of generator sets
operating in parallel.
