Question: Why Are Generators Rated In KVA And Not Kw?

Why are alternators rated in kVA and not in kW?

If we connect inductive or capasitive load (When power factor is not at least unity), The output would differ than as there are losses occurs due to low power factor.

For this reason, KVA is an apparent power which does not take in to account the PF (Power factor) instead of KW (Real Power).

And kVA = KW / Cos θ..

What is the difference between kVA and kW in generators?

kW is the amount of ‘actual power’ an electrical system has. This shows you how much power is being converted into useful, working output. kVA, on the other hand is the measure of ‘apparent’ power. If kW is how much power you can work with, kVA tells you how much is being used in the system overall.

What does kVA mean in generators?

kilovolt-ampereGlossary Term: kVA A volt-ampere (VA) is the voltage times the current feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical power is measured in watts (W): The voltage times the current measured each instant.

How do I convert kVA to kW?

The kW to kVA Formula: Apparent power (kVA) x power factor (pf) = actual power (kW) e.g. 100 kVA x 0.8 = 80 kW.

Why is motor rated in kW?

That’s why we are rated Motor in kW or HP (kilowatts/ Horsepower) instead of kVA. in more clear words, Motor only consume active power and provide mechanical power in HP or kW at motor shaft. … Moreover, the motor power factor does not depend on the load and it works on any P.F because of its design.
