Synchronization of generator

Synchronization of generators should done if it is connected to the National Grid. Before connecting a generator to the National Grid started generator should connect to the Synchronize cope then it should synchronize with the use of speed varying knob. Although the speed of the generator will vary by rotating the speed varying knob, after generator connect to the grid speed does not vary but the current drawn from generator to the grid will vary.

Auto Transfer Switch (ATS)

ATS is two big relays that use to connect main power supply or generator power to the load. To prevent two relays operate at a same time there is a mechanical lock between two relays also it prevent closing one relay while operating another relay. Although there is mechanical lock between two relays they will not energize at a same time by the Auto Mains Failure (AMF) board, lock will be useful it same malfunction will occur.
