Question

what are the different types of losses in transformer

Answer 1

Transformer is a device which transforms low voltage, high current AC power into high voltage, low current AC power.

$\underline{\bold{Its\: principle\: is\: based \:upon\: the}}$
$\underline{\bold{ phenomenon \: of \:mutual \:induction.}}$

The losses in transformer are as follows:-

$\underline{\bold{Flux\: loss}}$

A part of flux is generated in primary goes out of the secondary. It may be because of improper binding of the coil.

$\underline{\bold{Copper\:loss}}$

The primary and secondary both are generally made of copper and possess some resistance. When currents are induced in them, then due to joules heating a part of input power is loss in the form of heat.

$\underline{\bold{Eddy\: loss}}$

The core of Transformer remains in the varying flux continuously and due to this edition run on its surface. They are further cause of joules heating.

$\underline{\bold{Hysteresis}}$

Core of transformer is made by ferromagnetic substance and it remains in the cycle of magnetisation and demagnetisation. Due to the virtue of hysteresis, the core absorbs the amount of input power in every cycle, which is ultimately released to the surrounding in the form of heat.

$\underline{\bold{Humming\: loss}}$

With the change in polarity of AC, the core of transformer starts vibrating and produces a humming noise.
