*Why Transformer Rated In kVA, Not in KW? *What are transformer losses & their types?

Question

Accepted Answer

Transformers are rated in kVA because it takes into account both active power (KW) and reactive power (KVAR). Transformer losses include copper losses and iron losses.

Transformers are rated in kVA because they handle both active power (KW) and reactive power (KVAR).
kVA rating considers the total power (apparent power) that the transformer can handle, including the power needed for magnetizing the core.
Transformer losses include copper losses (I²R losses) and iron losses (eddy current losses and hysteresis losses).
Copper losses occur in the windings due to resistance, while iron losses occur in the core due to magnetic properties.
Efficiency of a transformer is calculated by dividing the output power (KW) by the input power (KW + losses).
