hree 20-kVA, 24000/277-V distribution transformers are connected in Δ-Y. The open-circuit test was performed on the low voltage side of this transformer bank, and the following data were recorded: Vline, OC = 480 V Iline, OC = 4.1 A P3φ, OC = 945 W The open-circuit test was performed on the low voltage side of this transformer bank, and the following data were recorded: Vline, SC = 1400 V Iline, SC = 1.8 A P3φ, SC = 912 W What is the magnetization reactance of this transformer, XM, in pu?
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.
