Question

Please kindly provide a detailed solution to the following problem with clear steps: Thanks in advance

A 3j load of 50 MW at 0.8 pf lagging is supplied at VLL 132 kV, 50 Hz by a 200km T/L. Series impedance of a single conductor is (20+j50)Ω, and the total phase-neutral admittance is j300 μ a. Calculate the sending end voltage, VS b. If load is removed but VS remains constant, find the percentage rise in VR and the sending end current IS
