In a 25KVA, 2000 / 200 V power transformer, the iron and full load copper losses are 375W and 405W respectively. Calculate the efficiency at (i) full load, 0.8 pf, (ii) half load, 0.55 pf, (iii) Quarter load, 0.55 pf Efficiency at Full load = Answer and unit for part 1 Efficiency at Half load = Answer and unit for part 2 Efficiency at Quarter load =
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.
