1. The following measurements were obtained from tests: carried out on a 10-kVA, 2300:230-V, 60-Hz distribution transformer: -Open-circuit test, with the low-potential winding excited: Applied potential difference, Voc = 230 V Current, Ioc 0.45 A = Input power, Poc = 70 W -Short-circuit test, with the high-potential winding excited: Applied potential difference, Vsc =120 V Current, Isc 4.5 A = Input power, Psc = 240 W Winding resistances, measured by dc bridge: = Rhp 5.80 2, R1p = 0.0605 2 (a) Determine the equivalent circuit of the transformer referred to the low- potential side.

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.
