(1)Why transformers rating is in kva ?

Question

Accepted Answer

Transformers rating is in kVA because it takes into account both voltage and current.

kVA is a unit of apparent power, which is the combination of real power (measured in kW) and reactive power (measured in kVAR).
Transformers are designed to handle a certain amount of power, and kVA rating takes into account both the voltage and current that the transformer can handle.
For example, a transformer with a rating of 100 kVA can handle a maximum load of 100 kW at a power factor of 1.0, or a maximum load of 80 kW at a power factor of 0.8.
kVA rating is also used to determine the size and cost of the transformer, as well as the size of the cables and other components in the electrical system.
Transformers are used in a variety of applications, including power distribution, voltage regulation, and isolation.
