what is kva
KVA is a unit of power. From ohms law it can be shown that in any circuit, the power of any element in the circuit is the product of the voltage and current (V x I) . Hence KVA is 1 Kilovolt times an Ampere and hence 1000 volts times an ampere. A unit of apparent power, equal to 1,000 volt-amperes; the mathematical product of the volts and amperes in an electrical circuit. A term used to describe the product of currend and voltage, expressed in kilovolt ampereres (KVA). KVA is the unit of transformer rating.
