ANS:
The electric power is now generated in the form of alternating current. The electric power is produced in the power station, which is generally very far from the consumer premises. So, the generation, transmission and distribution are facing much difficulty. It is distributed to the consumer or user by the help of a very large interconnected network. In the network it is very important to change some characteristics for transmitting and distributing the electric power properly. Such as, ac to dc conversion (by using thyratron and mercury arc rectifier), voltage up or down (If the generating voltage is 11kv then transfer it to the high voltage range of 220kv), frequency change, power factor correction and improvement. This change needs a setup of some apparatus properly, in short this types of setup is called substation.
The assembly of electrical apparatus whose purpose is changing the some major characteristics of the electric supply system is called substation.
The substation is very important for achieving the continuity of supply to the consumers. In some cases the ac is need to convert in dc for running the dc motor, traction, electroplating processes this type of conversion is performed by the sub-station (ignitron).
