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.
Replacing a Battery Bank
5.1 A protection plan is not required to complete replacement of a battery bank in a substation. However in some generation plants, turning off the battery charger DC output breaker may cause the plant lockout relay to trip. Therefore, it is necessary to contact the Power System Support Group to determine if a Protection Plan will be required

4 FAQs about [Bahrain substation battery bank]
How many substations will be built in Bahrain?
The contract has been signed with Saudi based Construction Company, Al-Babtain Contracting Company. The value of signed contract is BHD 21,508,133.743. As part of the package, there are fifteen (15) Substations that will be constructed across Kingdom of Bahrain.
What is a battery bank in a substation?
Overview In substations, battery banks are installed in order to provide reliable supply to control circuit breakers and measuring instruments. They are also used as back-up systems at a substation. Back-up systems form an important backbone of any system considering the backup supply and are of very high importance to utilities.
What are the different types of batteries used in industrial / substation applications?
In industrial or substation applications mainly three types of batteries are used namely: For UPS applications batteries are the most popular and hence are widely used. Hence, in this detailing, mainly emphasize has been put on these type of batteries. There are two types for vented or flooded lead acid batteries namely tubular and Plante.
How do SMF batteries work?
7. SMF batteries are equipped with a safe, low pressure venting system, which operates at 7 psi to 10 psi (can vary slightly from manufacturer to manufacturer), automatically releasing excess gas in the event that gas pressure rises to a level above the normal rate ensuring no excessive buildup of gas in the batteries.
