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.

Question

A 10 kVA, 2400/240 V, 60 Hz single phase
transformer has Z, = 5.2 + j12.5 ohms and
Z2 = 0.06 + j0.12 ohm. When operating at rated
primary voltage and frequency, the transformer
delivers rated current to its load at 0.8 pf lagging.
find the load voltage in volts. Neglect the no-load
current.
