You will notice that some electrical equipment express their power ratings in kW, or kilowatts; and some are expressed in kVA, or kilo Volt Amperes. Both values express power, but they are actually different. kVA is known as the âapparent powerâ of a particular circuit or electrical system. In direct current circuits, kVA is equal to kW, because voltage and current do not get out of phase. However, âapparent powerâ and âreal powerâ (which is expressed as kW) may differ in alternating current circuits.
