A single line diagram of a power system is shown in Fig.3.1. All the sequence reactances of the power system components are depicted in per unit on 20 MVA base, 110KV (L-L) in transmission circuit. If a single line to ground fault occurs on phase a through a reactance of 150 ohm at F, determine the current in ampere fed into the fault. The fault point F is assumed to be at 65% of transmission line length from the bus bar connected to generators A and B.

Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
