Power Output of a generator
Power Output of a generator
(OP)
Hi Guys,
A basic question about output power from a generator:
If I have a three phase generator supplying:
Red 10.5A
White 6.4A
Blue 9.5A
..and I take (240v*10.5)+(240v*6.4A)+(240v*9.5A) will this give me total power output in KW or in KVA? And then how does one get the other format?
Thankyou in advance,
Cam

Is there a formula to use for three phase that can make this calculation quicker?
For example 26.4Amps total. What equation can be used to calculate Total KVA?

RE: Power Output of a generator
KVA=3*V*I, where V = line to neutral voltage, not line to line
KW=3*V*I*pf, where pf = power factor of system
For an unbalanced system, which is what you have, there is no shortcut.
