A 400-k VA, 2300 230, 60-hz transformer supplies a 0.8 lagging power-factor load whose KVA Is adjustable from no load to 120 percent rated KVA. The percent resistance, percent reactance, and percent core loss are 56, 3.16, and 0.42 respectively. For 2 KVA increments of load, tabulate and plot the efficiency of the transformer from no load to 120 percent rated load. Please state the formulas clearly
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.
