A power transformer is used in the National Power Grid, where electricity is converted from alternating current (AC) to direct current (DC). As the demand for electricity grew, especially after World War II, utilities began to connect their transmission systems. To reduce energy transfers to the environment, the National Grid uses step-up transformers to increase the voltage from power stations to thousands of volts, which lowers the current in the transmission cables. Britain's distribution network operators connect the transmission network to where electricity is used, 'distributing' it a these lower, more usable voltages for our homes and businesses. The grid became a truly national system in 1938, a whole 10 years after that first pylon was erected. Austin, Texas, PUC Engineer (Engineer IV - VI) (00029045) In this way, step-up transformers help in supplying power to transmission lines; but this high voltage of electricity cannot be used by the end users.

Most of the balancing authorities are electric utilities that have taken on the balancing responsibilities for a specific part of the power system. Practical Significance of Step-Up and Step-Down Transformers The fact that voltage and current get stepped in opposite directions (one up, the other down) makes perfect sense when you recall that power is equal to voltage times current, and realize that transformers cannot produce power, only convert it. The power transformer is a device that converts bulk electrical power from one frequency to another. Why do we increase the voltage from 11kV to 132kv using step up transformer in grid sub station?
