What is the meaning of the transformer capacity unit KVA?
KVA for apparent power, its size and power factor!
For example: power factor cosΦ = 0.8 active power P = 1Kw
Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ
When the power factor is 1, 1KVA = 1KW
KV.A is the capacity in the transformer

The rated value of the output capacity of the transformer in the rated state is expressed in kilowatts (kVA) (VA and MVA are not commonly used). Since the transformer has a high operating efficiency, the rated capacity of the original and secondary windings Design values are equal.
