Figure QI shows a single line diagram of a power system and the associated data of this system are given in Table Q1. The per unit values are based on respective component's ratings. The load at transformer T: absorbs 65 MW, 0.85 lagging power factor, operating at 10.45 kV. (i) Using base of 100 MVA and 22 kV at generator G₁, construct an impedance diagram including the load impedance with all per unit values shown. (ii) If generator G₂ is disconnected by opening CB2, calculate the voltage at Bus 1.
