Reverse power relay manual

A reverse power relay is a protective transmitter that protects the turbine or motor from damage upon a reverse power condition. A generator can work as a synchronous compensator if the driving torque is less than the total losses in the system, taking necessary power from the network. Reverse power relays fitted to steam turbines are very susceptible to the small phase errors introduced by the instrument transformers. The motoring power is very small for a turbine spinning in near vacuum conditions, and it is quite possible for a heavy reactive load to cause the relay to behave is a digital relay. for reverse power detection of gen.-sets in parallel and. active power supervision of power systems. For generators operating in parallel with a mains or. another generator, it is imperative to supervise the. Protection Relays & Controls Catalog. We Are The GLOBAL EXPERTS in Electrical Safety and Productivity. This catalog outlines the Littelfuse line of protection relays, custom products, generator and engine controls, and alarm monitors, plus the technical capabilities we offer for your application. Reverse withstand voltage: Power voltage of the load circuit ? 10. Forward current: More than the load current. Note: Turn off the power to the relay coil when using the latching lever. • Not provided with an LED indica-tor, mechanical ag indicator, and manual latching lever. Reverse Power Relay is a Solid State Electronic Device used in a parallel operation of two generators. It is available for both three phase and one phase system with inbuilt Reset Both Auto and Manual reset models are available. Operation for both the models is explained in description given above.

There is not much difference between an alternator and electric motors from the engineer's perspective. The system is designed in such a way that it will release the breaker and prevent motoring of alternator if a reversal of power occurs.? ?

If you already bought a PROK Devices REVERSE POWER RELAY or just going to purchase it, it will be very useful to familiarize yourself with the instructions for its useing and maintenance. The Selco Reverse Power Relay T2000 will, during parallel operation, prevent the generator from running as a motor. Certified for marine use. 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.
