Short-circuit kVA and X/R may need to be derived from other data. Short-circuit current (ISC) is sometimes supplied by the power company rather than short-circuit kVA. This current is the current in one phase of a three phase bolted fault. The short-circuit kVA can be calculated from the short-circuit current using the following equation. (Eq. 1)
kVA Calculator | Single, Three Phase kVA Calculator
kVA is kilo-volt-ampere. It is an unit of apparent power used in obtaining the electrical capacity of circuit breakers and wirings. One kilo-volt-ampere is exactly equal to 1000 volt-ampere. Here volt is an electrical pressure and amp is an electrical current. Use our online Single, Three Phase kVA Calculator to find the KVA …
