What is difference between kW and kVA?

kW is the amount of power capable of doing work, while kVA is the “vectorial summation” of KVAR and KW. kW is kilowatts, while kVA is kilo Volts Amperes. kVA is equal to kW in DC circuits because the voltage and current are in phase. In AC circuit at unity power factor KVA=KW.

Considering this, how much is 1 kVA in Watts?

Is a kVA the same as kW?

The ratio between the VA (i.e. rms volts time rms amps) and Watts is called the power factor PF. In other words, volt-amps x power factor = watts. Similarly, KVA*PF = KW, This is because VA considers the peak of both current and voltage, without taking into account if they happen at the same time or not.

What is difference in kW and kVA?

The primary difference between kW (kilowatt) and kVA (kilovolt-ampere) is the power factor. kW is the unit of real power and kVA is a unit of apparent power (or real power plus re-active power). For example if you have a 500 horsepower engine it has a kW rating of 373.
