A 20 kVA, single phase-phase, 50 Hz, 2200/200 V transformer gave the following test results: O.C. test: 2200 V, applied to primary; power input 220 W S.C test: powersequired to dirculate full-load current in short-orcuited secondary 240 W. Find the efficiency at full-load and half full-load at power factor of 0.8 lagging.?
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.
