Question

describe the different from of energy loss in a transformer

Answer 1

Energy Losses In Transformer. Although transformers are very efficient devices, small energy losses do occur in them due to four main causes: Resistance of windings – the low resistance copper wire used for the windings still has resistance and thereby contribute to heat loss. ... The eddy currents cause heat loss.

Answer 2

Transformer losses are produced by the electrical current flowing in the coils and the magnetic field alternating in the core. The losses associated with the coils are called the load losses, while the losses produced in the core are called no-load losses.
