Here is the KVA formula for single and three phase transformer which guides you to calculate the single phase and three phase. Use the formula, (kW = kVA * power factor) to find the result. KVA power measures the apparent power obtained by multiplying the voltage times the current, even when they are out of phase. The most important three-phase power equations relate power (P, in watts) to current (I, in amps), and depend on the voltage (V). For the reverse process, use the form of the equation given above: P = √3 × pf × I × V. Simply multiply your known values together to find the answer. Table of kVA to kW for three-phase transformers (Power factor of 0.8): The transformers are designated by kVA and not by kW, this is because the transformers can have almost any kW and the latter will depend on the load, for example, if the transformer is 225kVA, it can have 200kW, 150kW, 100kW, 50kW , 20kW, etc. 1000 volt-ampere is called as one kilo-volt-ampere. The below section of this page provides you the three-phase transformer capacity formula which helps you to calculate the capacity of a 3 phase transformer with the known values of kVA, volts, and amps.
