Answer 1

Answer:

Types of Energy Losses in a Transformer

Losses in a Transformer.

Copper Losses (Winding Resistance)

Core or Iron Losses. a) Hysteresis Losses. b) Eddy Current Losses.

Stray losses (leakage Flux)

Dielectric Loss.

Other Losses. Magnetostriction Losses. Mechanical losses.

Answer 2

The energy losses in a transformer are as follows:

(i) Hysteresis loss : This is due to the repeated magnetisation and demagnetisation of the iron core caused by the alternating input current. This can be minimised by using alloys like mumetal or silicon steel.

(ii) Copper loss : Current flowing through the primary and secondary windings lead to Joule heating effect. Hence some energy is lost in the form of heat. Thick wires with considerably low resistance are used to minimise this loss.
