In substations, DC supply is by and large utilized for driving control circuits. You could ask why we use DC or why not AC all things being equal. Allow me to make sense of the primary explanations behind involving DC in power substations.
Indoor Substation : The essential justification behind utilizing DC power supply in the control circuit is to provide a continuous power supply to the control hardware.
Since DC power can potentially come from batteries, it is a reliable source. As long as the battery is kept charged, it can provide power continuously. Because batteries can hold electrical energy, they are a suitable option for a reinforcement power source.
A substation contains a number of control circuits that are kept in the On state to operate switchgears, circuit breakers, isolators, and transfers.
If we use an alternating current (AC) supply and a power outage occurs, we will not be able to provide power to the control circuit. In the event of a power outage, when all devices stop working, we will be unable to investigate problems, circuit breakers, or hand-off situations. In any case, during a blackout, we want to ensure that the control circuit receives continuous power. Because we can provide power through batteries, and batteries can supply DC power, the entire control hardware is designed for DC supply.

Different purposes: In a substation or power station, DC power is also used to operate circuit breakers (opening and closing them), protective transfers, isolators, marker lights, warning circuits, PLCC (Electrical Cable Transporter Correspondence) board, crisis lights in the control room, and that is just the tip of the iceberg.
Defensive devices respond much faster when powered by DC rather than AC. Static devices that require a DC power supply can be easily connected to batteries. However, when using an alternating current power supply, a rectifier circuit is required. Control circuits include a variety of advanced devices such as computerized displays, sensors, LEDs, and so on, all of which require a direct current supply. Thus, using a DC supply in the control circuit reduces the need for complicated hardware.
Overall, DC voltage is critical at substations due to its dependability, particularly in powering control circuits and providing reinforcement power. Its application considers improved activity and the board of the substation's equipment and gadgets.
Isolator Motor drive box can be operate by three ways on is remote opertated by contral cables , 2nd is localy operated from operation box and third from Mechanically with a handle attached to the operation box . Motor opration box is required three sourcse of supply 1 is three phase AC for its Motor, Single phase supply Motor drive operated Isolator is operated remotely with control panel which is more safe practice in substation. In this Operator is out of live circuit of High voltage .
