A short-circuit test has been carried out with a three-phase transformer of 30/6.5 kV. By experiment, the high-voltage side was short-circuited and it was read: Ik=30A, Uk=234V and Pk=5.24kW a) Find the nominal voltage drop in % for this transformer where a was measured power factor of 0.8 ind. Under a certain load of the transformer, we measure a voltage drop of 5%, when the primary side is at 30kV. b) Find the secondary clamping voltage at this particular load
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.
