KW vs. KVA
KW vs. KVA
(OP)
I'm an HVAC engineer and work mostly with KW's when specifiying power loads. I have seen loads referenced in terms of KVA. What is the difference? Is there a simple conversion?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: KW vs. KVA
W = Active Power
VA = Apparent Power
pf = W/VA ; pf is the power factor of the system or equipment (power efficiency). Hope this help you...

KVAR is the "circulating" portion of KVA.
A factor which is called as power factor determines this sharing. Less circulating energy(kVAR) results more usable energy(kW). Because their vectoral sum (KVA) is constant for any given machine.
