In a transformer, there is a certain amount of loss in load that is to be taken into consideration. The factors included in this prospect are eddy currents with respect to secondary and primary conductors as well as amount of heat loss levels.

There are 2 types of losses in case of a transformer: Amount of copper loss as well as iron loss. The iron loss amounts to lossin terms of its core value.

**Copper loss:**

The primary reason for this loss is its presence of ohmic resistance which is present in transformer windings. Also, as per scientific value, these losses are in proportion to current’s square value. It is with a short-circuit test that will result in your finding of total value of copper loss amount.

**Core/Iron loss:**

In this category of loss, 2 points are to be taken into consideration. Eddy current loss as well as Hysteresis loss. Also, an open-circuit test is required in this case, with core loss is measured via no-load process.

In case of Eddy current loss: It is taken into consideration that there is a certain flow of eddy currents via a thin insulation that will result in loss of this current in a minimal proportion.

In case of hysteresis loss: It is a scientific fact that flux that is present within a core of a transformer has alternating power. Thisis incessantly required for constant reversals for magnets that are elementary, and it helps in composing of iron.

While dealing with such losses, it is important that all these factors are taken into consideration.
