7. Two single-phase transformers work in parallel on a load of 750 A at 0.8 p.f. lagging. Determine secondary voltage and the output and power factor of each transformer. Test data are: Open circuit: 11,00/13,300 V for each transformer Short circuit: with h.v. winding short-circuit Transformer A: secondary input 200 V, 400 A, 15 kW Transformer B : secondary input 100 V, 400 A, 20 kW [3,190 VA : 80 KVA, 0.65 lag; B: 1,615 kVA ; 0.86 lag]
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.
