A Three-phase generator step-up bank transformer is rated 1000 MVA, 13.8 kV Y/500kV; with Zeq 4.38 pu. the Generator/step-up transformer feeds a load of 345kV rated. As typical in practice, the transformer taps are adjusted in steps, with each step changing the tap ratio by 0.625%. Because of the varying voltage drops caused by changing loads. LTCs should be operated to regulate the bus voltage. What is the minimum current in the transmission line for 500MW/100Mvar load?
