A power transformer is usually rated in____________?
Correct answer: D. kVA
- A. kW
- B. kVAR
- C. kWh
- D. kVA
Explanation
A transformer is rated in kVA because its heating is determined by voltage and current, while its losses do not directly depend on the load power factor. Real power in kW varies with the connected load power factor.
