A generating station has 4 sections busbars. Bach section busbar has a generator connected to it of rating 5000KVA,10% reactance and also each busbar is connected to a tibbar through reactors each having 7.5% reactance based upon the rating of the generator counected to it. Find the short circuit KVA, when thore is a 3-phase fault between the lines on one of the sections of busbars (a) with and (b) without reactors. Ans: (a) 87,500KVA (b) 200,000KVA
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.
