Why transformer are rated in KVA.

Question

Accepted Answer

Transformers are rated in KVA because it represents the apparent power they can handle.

KVA stands for kilovolt-ampere, which is a unit of apparent power.
Transformers are designed to handle a certain amount of power, and the KVA rating indicates their capacity.
The KVA rating takes into account both the voltage and current that the transformer can handle.
It helps in determining the appropriate size and capacity of the transformer for a given application.
For example, a transformer with a 100 KVA rating can handle 100,000 volt-amperes of apparent power.

Accepted Answer

total transformer heat loss depends on volt-ampere (VA) and independent of phase angle among voltage and current i.e., it is independent of power factor.

Accepted Answer

We connect multiple electrical loads having multiple power factor in transformer and KW depends on power factor and for transformer power factor is variable . So, KW will be variable and hence it should be rated as KVA.

Accepted Answer

Yes transformar are rated in kva

Accepted Answer

Transformer are rated in KVA because we know that transformer has two loss one is veriable loss i.e depends current and another one is constant loss i.e depends voltage.
