A 3-phase, 10KV, busbar of a power station is divided into three sections joined by two reactors as shown in Figure 1. Each section contains a synchronous generator and supplies a transmission line through a transformer. The parameters of genera-tors, reactors and transformers are given in Figure 1. Calculate the maximum initial fault line current which can flow into the fault, if a 3-phase short-circuit occurs in: A
