The voltage of power generated at the generating stations is first stepped up before its transmission. Give reason.

 

Best Answer

Usually at 11 kV, power generated at generating stations which is very high. This power is to be transmitted across far away distances from the generating stations. A lot of energy is lost in the transmission line wires in the form of heat during transmitting the 11 kV power. Hence, using the step up transformer the voltage of power generated at the stations is stepped up from 11 kV to 132 kV. This process is applicable only for alternating current since direct current cannot be raised.
