Given: A single-phase two-winding transformer is rated 20 kVA, 480/120 volts, and 60 Hz. The equivalent leakage impedance of the transformer referred to the 120-volt winding, denoted winding 2, is ???2 = 0.0525∠78.13°?. Find: Using the transformer ratings as base values, determine the per-unit leakage impedance referred to winding 2 referred to winding 1.
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.
Given:
A single-phase two-winding transformer is rated
20 kVA, 480/120 volts, and 60 Hz.
The equivalent leakage impedance of the transformer referred to the 120-volt winding,
denoted winding 2, is ???2 = 0.0525∠78.13°?.
Find:
Using the transformer ratings as base values, determine the per-unit leakage impedance
referred to winding 2
referred to winding 1.
