Electrical substation layout is a process which involves transmission, generation as well as distribution system. Besides, the word substation is known to come from the days before the distribution systems became a grid. This type of layout also, changes the voltage rates between low distribution voltages and high voltage distribution voltages.
It is very important to generate electricity in low voltage level. While on the other hand, it is more economical also to transmit power at a high voltage level. In most cases, electrical substation layout is done at a very lower levels .However, in order to maintain the voltage levels as well as enhancing greater stability; switching stations needs to be created or invented in between the consumer ends and the generating stations.
There are various classifications of electrical substation layout. The substations are named depending on their purpose or the voltage associated with. Those which requires high voltages carry out different functions as well as the low voltage ones.
