The nominal specifications seen on the nameplate of a single-phase transformer are 600 MVA, 95/500 kV, resistance of 2.3% and a reactance of 7%, the magnetizing reactance is 125 pu. The voltage regulation of the transformer, for a full load current with a power factor of 0.92 lagging is: a) 5,45% b) 6,87% c) 5,03% d) 6,97% e) 8,36%
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.
