A 10 MVA three phase load is to be served by a three phase transformer at a line voltage of 13.8 kV. The supply side voltage(line-line) is 138 kV. Various single phase transformers are available in the warehouse but all have windings with voltage ratings under 100 kV and current ratings under 250 A. Is it possible to serve the load using only three single phase transformers? If so, specify the three phase connections and the low and high voltage ratings of the single phase transformers.
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.
