A 400-MVA, 240-kV/24-KV, three-phase Y-A transformer has an equivalent series impedance of 1.2 + j6 per phase referred to the high-voltage side. The transformer is supplying a three-phase load of 400 MVA, 0.8 power factor lagging at a terminal voltage of 24 kV (line to line) on its low- voltage side. The primary is supplied from a feeder with an impedance of 0.6 + j1.2 per phase. Determine the line-to-line voltage at the high-voltage terminals of the transformer and the sending-end of the feeder

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.
