uses of transformers

What is the use of power transformer in substation?

In: Electrical Engineering [Edit categories]

Answer:

Power transformers are used in electricity transmission systems to either step up, or to step down, system voltages. They step up the voltage produced by the alternators in the power station to the very high levels necessary for transmission, then gradually step down the transmission voltages at substations located in and around load areas (e.g. near cities, etc.).
