A normal transformer has a nominal 60 kVA. The nominal primary and secondary voltages are 600 V and 120 V respectively. If this transformer is connected as an autotransformer at 600 Vac a-) What would be the output voltages available using different connections? b-) Calculate the load kVA that the transformer can supply for each of the output voltages. c-) Calculate the currents of the windings for each one of the output voltages, indicating if it exceeds the nominal values.
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.
