2. A 60 kVA, 2400/415 V, 60 Hz single phase transformer has the following parameters: R₁ = 2.4 X₁ = 4.6 R₂ = 0.06 X₂ = 0.02 | =44200Ω Xm : 7800 Ω Rfe The transformer is delivering at 90% rated load and also at rated voltage with 0.85 power factor lagging. Based on the given data, a) Compute all the transformer parameters referred to the primary side. (12 marks) b) Sketch the labelled exact equivalent circuit referred to the primary side. c) (4 marks) Compute the transformer voltage regulation at 90% of rated load. Ignore the Holtage drop at primary winding. (4 marks)
