Two single-phase 11,000/400 V transformers have kVA ratings of 200 kVA and 100 kVA respectively. The equivalent resistance and reactance of the 200 kVA transformer are respectively 1 and 5 ohms when referred to the 11,000 V side. The equivalent reactance of the 100 kVA transformer referred to the 11,000 V side is 9 ohms. What should be the equivalent resistance of the 100 kVA transformer if each transformer is to supply a load in proportion to its kVA rating when operated in parallel?
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.
