Why is the rating of TRANSFORMER written in VA, KVA, MVA 2022

The transformer has two types of losses such as:

1. Copper loss

2. Iron loss or core loss or insulation loss

The copper loss depends on current (R) and core loss depends on voltage.

So Laid using current. Then the power factor depends on the load. Laid resistant or inductive or capacitive that

Corners can be kind. And with a transfer, there are different types of loads. There are different types of power factors for this.

Power cannot be extracted without the power factor. The equation of power is that the value of w = 3VICOS%.COs) is unknown, so we do not get the value of W. So the unit of voltage is V, and the division of current is A And there is no unit of power factor in it.
