A three-phase, 230 V, 72 kVA, 0.9 pf (lagging) load is supplied by three 29 KVA, 1330/230 V, 60 Hz transformers connected in Yd5 by means of a common three-phase feeder with an impedance of 0.003+j0.015 ohms per phase. The transformers are supplied from a three-phase source (substation) through a three-phase line with an impedance of 0.55+j4.6 ohms per phase. The equivalent impedance (Rsc +jXsc) of one or the single-phase transformers referred to the low-voltage side is 0.16+j0.32 ohms. (a) Deter- mine the required supply voltage if the load voltage is 230 V. (b) Determi voltage

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.
