At the end of a one-phase supply line with a series impedance of 1+j2 ohms, a 50 kVA, 2400/240 volt, 60 Hz, distribution transformer is used as a step-down transformer and feeds the load shown in the one-phase figure. The equivalent series impedance of the transformer transferred to the primary is 1+j2.5 ohms. a) Find the voltage at the primary ends of the transformer? b) Find the primary voltage supplied to the feeder? c) Find the apparent and reactive power drawn from the feeder?
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.
