kVA - The kVA, or Kilovolt-ampere, output rating
designates the output which a transformer can deliver for a specified
time at rated secondary voltage and rate frequency without exceeding
the specified temperature rise (1 kVA = 1000 VA).
Kvar - A term used to express the power rating
of a capacitor. KiloVolt Ampere Reactance, expressed by the following
- Kvar = [2 x pi x f x c x kV x kV]/1000
pi = 3.14159
f = frequency (hertz)
c = capacitance (in microfarads)
kV = kilovolt
kW - Kilowatts. Real power delivered to a load
(W x 1,000 VA).
