SAMPLE SPECIFICATION:
Protection from damage, caused by reverse power into the
generator of the three phase power generating system, shall
be accomplished by the use of a Reverse Power Relay. The
relay shall incorporate single phase sensing to detect the
power reversal and remove the generator from the bus. The
relay shall be capable of operation on a nominal 120 volt (or
139, 240 or 277) single phase, 60 hertz power source.lt shall
be easily mounted directly on the generator and be capable
of withstanding
5
Gs at 60 hertz. The relay shall provide
adjustable pickup sensitivity between 0.10 and 1.67 am
peres and an adjustable time delay between 0.2 and 4.0
seconds at twice the pickup input value. It shall include an
automatic reset. The output contacts shall be rated at 10
amperes at 120 Vac.
