Electrical power systems nowadays are generated, transmitted, and distributed in the form of alternating current. The electric power is produced at the power stations which are located in suitable places, generally quite away from the consumers.
It is delivered to the consumers through a large network of transmission and distribution. At many places in the line of the power system, it may be desirable and necessary to change some characteristics (e.g., voltage, AC to DC, frequency, power factor [pf], etc.) of electric supply.
For that, in between the power station and ultimate consumer, a number of transformations and switching stations have to be created. These are generally known as .
The assembly of apparatus used to change some characteristic (e.g., voltage, AC to DC, frequency, pf, etc.) of electric supply is called a substation. Substations are important part of power system. The continuity of supply depends to a considerable extent upon the successful operation of substations.
There are several ways of classifying substations. However, the two most important ways of classifying them are according to (1) service requirement and (2) constructional features.
