Protection Relays & Controls

Generator & Single-Function Protection–Reverse Power

T2000 SERIES

Reverse Power Relay

Description

Under parallel operation, the T2000 Reverse Power Relay will

protect the generator from being run as an electric motor.

The T2000 will protect the prime mover of the generator

against physical damage, but will also protect the parallel

running generators from overload caused by the inversed

load shift in a reverse power situation.

The T2000 calculates I x cos F representing the active

power. If the active power becomes negative and exceeds

the preset level (2-20%), the pick-up LED will indicate

this and the delay timer will be started. After the preset

time (2-20 sec.) has expired, the output relay and LED will

be activated, provided that the reverse power level was

exceeded for the entire delay time.
