THREE PHASE TRANSFORMER

HOW WILL YOU REDUCE CORE LOSS IN THE TRANSFORMER?

• By using silicon steel

• By reducing the size of winding

• By increasing the size of the winding

WHICH IS VARIABLE LOSS IN THE TRANSFORMER?

• CORE LOSS

• COPPER LOSS

• STARY LOSS

HOW WILL YOU REDUCE THE HYSTERESIS LOSS?

• By increasing the size of the winding

• By reducing the size of the winding

• By using thin silicon steel

HOW WILL YOU FIND OUT THE CORE LOSS?

• BY CONDUCTING SHORT CIRCUIT TEST
