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.

Notes:

1.

Remove screw for access to the pick-up adjustment.

2.

Clockwise rotation of the adjustment will raise the reverse trip point.

3.

This relay senses true power, which is a product of voltage, current and phase angle.

Connections and polarity must be obversed in accordance with the provided diagrams.
