A generator rated 1MVA
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.
A generator rated 1MVA, 13.8 kV 60 hz 3-phase wye connected, 6-poles has 19Ω synchronous reactance per phase and negligible resistance. The field copper loss and SPL are 15 kW and 30 kW respectively. Determine the % VR and efficiency of the generator at rated load and unity power factor
