(c) A balanced Y-connected load with a phase resistance of 12 A series with reactance of 15 A is supplied by a balanced ABC-phase sequence delta-connected source with a voltage line of Vab-400445°V. Between the supply and load has 4 A resistance each line. (i) Sketch the circuit diagram of the system. (ii) Draw the three-phase Y-Y connected equivalent circuit. (iii) Calculate the phase currents of the source.

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.
