The resistance of a 500 kva, 11000/2300 volts 60 Hz transformer are respectively 0.8 and 0.04 ohm for high and low voltage sides. The iron loss is 3,000 watts. This transformer is loaded daily as follows: 2 hrs at full load, 3 hrs at three quarter load, and 6 hrs at one-quarter full load. Calculate the all day efficiency in percent. (Assume unity power factor at all loads)
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.
