DC Power Supply System in an Electrical Substation
The battery bank provides the DC supply to load only in case the Battery charger breaks down or the AC supply to the battery charger breaks down. So in normal conditions, it is the charger that supplies DC power to protection, communication, control, and measurement devices running in the Electrical substation & not the battery bank.
Why Battery Bank is Used in Substation
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
