Why Motor rated in KW instead of KVA?
The induction motor and the transformer work on the same principle, that is, Faraday’s law of electromagnetic induction. The motor is rated in kW instead of KVA,
Electrical
What is the Difference between kW and kVA?
kW is the unit of active power that is consumed by the load for doing real work. The real power drawn from the system is
