Question

Core loss of the transformer can be reduced by

Answer 1

There are two types losses :

1. Copper loss

2. Core loss 

a. Hysteresis loss

b. Eddy current loss.

Copper losses are due to induced current in the winding due to which heating effect is produced, copper loss cannot be eradicated completely but can be reduced  by using windings made up of copper.

Core losses:

a. Eddy current losses can be reduced by laminating the core properly.

b. Hysteresis losses can be reduced by reducing the area of hysteresis loop

Answer 2

hey mate here is your answer!!!

core loss of the transformer can be reduced by using silicon steel as the core metal and also by using laminated Steel sections for core instead of solid sections.
