The following data pertain to two three-phase, parallel-connected, 2,2 kV alternators that are on no load: Machine A: 300 kVA, Xs = 20% Machine B : 500 kVA, Xs = 30% The excitation of A is reduced so as to circulate its full-load current. Assume the machines remain synchronised and calculate: (a) the induced emf of machine A (b) the terminal voltage
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.
The following data pertain to two three-phase, parallel-connected, 2,2 kV alternators
that are on no load:
Machine A: 300 kVA, Xs = 20%
Machine B : 500 kVA, Xs = 30%
The excitation of A is reduced so as to circulate its full-load current. Assume the
machines remain synchronised and calculate:
(a) the induced emf of machine A
(b) the terminal voltage
