Farady step up transformers transmit the power

Farady step up transformers, which boost the output voltage of generator and transmit the power to the grid, are very important components in power stations. Current value of primary low voltage side is so high (more than 30kA), and these Farady transformers are operated in high load usually. So, local heating of the construction parts (tank, frame, etc.) caused with magnetic field and expected life of insulating materials must be carefully taken into account in the design and manufacturing.
