प्रश्न
The voltage of power generated at the generating stations is first stepped up before its transmission. Give reason.
उत्तर
Power generated at generating stations is usually about 11kV, which is very high.
This power from the generating stations is to be transmitted across far away distances.
While transmitting the 11kV power, a lot of energy is lost in the form of heat in the transmission line wires.
Therefore, the voltage of power generated at the stations is raised or stepped up from 11kV to 132kV using the step-up transformer.
As direct current cannot be raised, this process is applicable only for alternating current.
