Q2. (a) Explain what is per unit system? What are the advantages of per-unit computations? Prove for the problem given in part (b) that PU impedance of the circuit element connected by the transformers expressed on a proper base will be same if it is referred to either side of a transformer. (b) A 3-phase, A-Y transformer with rating 100 kVA, 11 kV/400 V has its primary and secondary leakage reactance as 122/phase and 0.05N/phase respectively. Determine the PU reactance of transformer referred to primary side and then secondary side to prove that it will be same.

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.
