Question

Q. A 150-kVA, 2400/240-V, 60-Hz, single-phase transformer has the following parameters: R₁ = 0.2 , R₂ = 0.002 , X₁ = 0.45 , X₂ = 0.0045 , RC = 10 k, and Xm = 1.55 k, where the notation is that of Figure. Form the equivalent T-circuit of the transformer referred to the high-voltage side, and calculate the supply voltage on the high-voltage side when the transformer supplies rated (full) load at 240 V and 0.8 lagging power factor.
