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.
