In an experiment for determining the breakdown strength of transformer oil with standard electrodes, the following observations were obtained with two different types of oils (Oil A and Oil B). Oil A breakdown voltage is 165KV at 8mm gap spacing and for the same gap space Oil B break down Voltage is 0.140MV. For 16mm gap spacing, the breakdown voltage is 212 KV and for the same gap spacing, Oil B breakdown voltage is 200KV. Determine the power law for breakdown and hence estimate the breakdown strength for a 4 cm gap (kV/cm).

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.
