A single phase transformer rated 30 kVA, 1200/120 V is connected as an autotransformer to supply 1320V from a 1200 V bus (a) Draw a diagram of the transformer connections showing the polarity marks on the windings and directions chosen as positive for current in each winging so that the currents will be in phase. (b) Mark on the diagram the values of rated rated in the windings and at the input and output. (c) Determine the rated kVA of the unit as an autotransformer (Ctr) -

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.
