Question

What are four different types of energy losses in a transformer? State how to reducel minimize any one of them.

Answer 1

Four types of energy losses in transformer are $\left(1\right)$ Copper loss, $\left(2\right)$ Eddy current loss, $\left(3\right)$ Hysteresis loss, $\left(4\right)$ Flux loss.
Copper Loss: This loss can be reduced by increasing the cross-sectional area of the conductor or by reducing the winding length.
