Why is the transformer rated in kVA, not in KW

Answer: Transformers are rated in kVA (kilo-volt-amperes) instead of kW (kilowatts) because kVA accounts for both real power (kW) and reactive power, which is essential for sizing and designing electrical systems. Reasoning: Transformers are devices used to transfer electrical energy between circuits. They handle both real power (expressed in kilowatts, …
