The T2000 Reverse Power Relay will protect the generator from being run as an electric motor. The Reverse Power Relay will protect the prime mover of the generator against physical damage, and will also protect the parallel running generators from overload caused by the load shift in a reverse power situation.

The T2000 Reverse Power Relay measures the current through an external 5A CT attached on phase Line 1. The phase angle is determined from the voltage measurement across Line 1 and Line 2. The T2000 calculates the active current as I x cos phi. If the active current becomes negative and exceeds the preset level (2 – 20 %), the pick-up LED will activate and the trip delay timer (2 – 20 seconds) will also activate. The built-in trip relay will energize after the delay has passed, provided that the preset trip level was continuously exceeded during the time of the delay.
