How to size a control power transformer

WebJul 11, 2024 · Single Phase Transformer Example: V = 240, I = 175; Therefore: kVA = (240 x 175) / 1000 = 42 kVA This calculates to 42 kVA, thus we round up to a standard Single Phase size 50kVA. From the Digest, an EE50S3H will satisfactorily serve this load. Three Phase Transformer Example: V = 208, I = 175; Therefore: kVA = (208 x 175 x 1.732) / 1000 = … WebTo calculate the rating of a single-phase transformer with a load voltage of 240 volts and maximum load phase current of 175 amperes: The kVA rating of the transformer = V × I = 240 × 175 = 42kVA. Dividing the kVA by 0.8, revised kVA= 52.5. Hence, a transformer with a kVA rating of approximately 53 can be used for the load.
