Star delta starter interview question
In this video we explain star delta starter interview question which generally ask in electrical interview
So we explain why we use star delta starter
So generally star delta use to run more than 10 HP motor and starting current can be use by this starter so explain answer
2)star delta starter motor terminal connection explain to give 440v to each of three coil
3)how starting current can reduce by star delta starter
So when we run motor so first our motor run in star and after motor speed it transfor to delta
4) when motor trip in star delta starter so what to do
So first check mcb and contactor is it any single phasing or not
Than check motor
After this check timer timing
Than check motor connection
So explain all point very easily for more information learning about this topic just watch and learn
