ACCUM- 31/33 REVERSE POWER RELAY

When two alternators are running in parallel and if engine of any of the alternators develops trouble then the other good alternator will force drive the damaged engine by making the alternator of the damaged engine run as a motor and thereby result in a severe damage to the second engine.

These Relays provide a sensitive, accurate and economical protection against motoring conditions in diesel alternators and back pressure turbines.

SPECIAL FEATURES:-

	Extremely fast tripping during severe faults.
	Prevents inadvertent tripping due to short duration of minor motoring action caused by sudden loss of load or due to maladjustment of throttle settings of two engines.
	It is extremely simple in construction thereby making maintenance most easy.
	It is immune to voltage surges normally occurring in D.G. Sets.
	It is type tested to IS-3231
	It is suitable to operate up to 50° C Ambient temperature which some times do occur in engine rooms.
	Relays are provided with standard 230V AC auxilliary voltage rating and there is no need to provide auxilliary D.C.supply unless required.

MAXIMUM TORQUE ANGLE:

Develops maximum torque when the applied voltage lags the applied current by 30° . It can operate even at Extremely Low Power Factors Occurring during severe faults.
