WebkVA calculation. To calculate the kVA we need to know at least the line-to-line voltage (V) requirement of the load and the maximum load phase current (I). For a single-phase transformer, kVA = (V x I) /1000. For a Three-phase transformer, kVA = (√3 x V x I) /1000 = (1.732 x V x I) /1000. Are you struggling to calculate amperage of your load? WebTransformer calculator. Input the values of ampere and voltage. Then to calculate KVA (rating) choose between three-phase and single-phase from the Transformer calculator. This 3 in 1 calculator helps users to find the current, voltage, and rated phase power of the step up and step down transformer. you can choose to find any of these values.
