1010603 IntroductionT.K. GanguliThe history of transformer goes back to the early 1880s. With the sharp increase in demand for electric power, power transformers in 400 kV ratings were produced as early as 1950. In the early 1970s unit ratings as large as 1100 MVA were produced and 800 kV and even higher kV class transformers were manufactured in the early 1980s.A transformer is a static piece of equipment with a complicated electromagnetic circuit inside. The energy is transferred from one electrical circuit to another through the magnetic field. In its simplest form, a transformer consists of two conducting coils having a mutual inductance. In an ideal case it is assumed that all the flux linked with th…
