A substation generally has switching, protection and control equipment and one or more transformers.
The transformer is an electric machine that works on the principle of electromagnetic induction. It transfers the electrical energy from one electric ckt to another with the help of the magnetic path (flow) at the constant frequency but the same or different voltage voltages. To this end, two sets of insulated windings are wound in a finished steel core. The winding that is connected to the power supply is called the primary winding and that the winding is connected to the load is called the secondary winding.
