How to size a current transformer

WebTransformer impedance dictates how much fault current a transformer can supply to a fault for a given kVA size. The higher the impedance, the lower the available fault current. Sometimes transformer impedances are used to limit the let-through current (sometimes called the infinite bus fault current calculations). WebApr 11, 2024 · The formula for both three-phase and single phase transformers is given below. 3 phase transformer current is equal to: I3ph = P3ph / (√3 × V3ph) Where: I3ph [kA] = the current flowing through the windings. P3ph [kVA] = the rated 3 phase power of the transformer. V3ph [kV] = the 3 phase voltage at the windings.
