Synchronous check relay
WebSynchronous check- Synchronous check is for two power sources, like two generators or a generator and wall power, where a connection or switch between them will have both connected at the same time. This type of relay will check to make sure the phase is aligned so the user can perform this switching. Features. Webfalse. A (n) ___ relay is an overload relay that is used to protect a synchronous motor from damage from induced currents caused by the rotor falling out of step with the rotating stator field. out-of-step. A (n) ___ resistor is a resistor used to discharge any AC potential that builds up in the DC field winding of a rotor in a synchronous motor.
