  • How to Calculate the Rating of Transformer Electrical

    Aug 22 2018 · The power factor of load may be assumed to be 0.85. Suppose the load requirement of a utility to be fed is 85 kW then the kVA rating of transformer should be (85/0.85 = 100). Again if the source voltage is 11 kV and load is to be fed by 415 V then the rating of transformer will be 100 kVA 11 kV / 451 V. Transformer rating = 100 kV.
