2. The sequence reactances of a three phase alternator are X1 = x2 = 0.15 and Xo = 0.05 pu, based on the machine rating of 30MVA and 13.2 kV. The alternator is connected to a transmission line having X1 = X2 = 0.1 pu and Xo = 0.4 pu. A line to line fault occurs on the line at the receiving end. Draw the sequence networks for the faulted system and calculate the fault current.

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.
Question
Transcribed Image Text:2. The sequence reactances of a three phase alternator are X1 = X2 = 0.15 and Xo = 0.05 pu, based
on the machine rating of 30MVA and 13.2 kV. The alternator is connected to a transmission line
having X1 = X2 = 0.1 pu and Xo = 0.4 pu. A line to line fault occurs on the line at the
receiving end. Draw the sequence networks for the faulted system and calculate the fault current.
