6 FAQs about [Mali substation battery bank]
How are substation battery banks purchased?
The substation battery banks are sized and purchased by the substation engineering activity. Battery banks are purchased direct from pre-approved battery bank manufacturers. Battery banks are purchased for individual substation projects and for replacement of deteriorated existing banks throughout the system as needed.
Where do batteries go in a substation?
In large substations, the batteries may be out in the middle of the floor with the pan protruding all the way around the battery rack. Erroneously, the measurements for the required working space about the batteries are many times taken from the terminals of the batteries.
What are the different types of battery banks used for substation applications?
There are two major types of battery banks used for substation applications; lead acid and nickel cadmium. The nickel cadmium battery banks are about twice the cost of lead acid for the same size bank. The major advantage that nickel cadmium batteries have over lead acid is their performance in poor climatic conditions.
Where are battery banks purchased?
Battery banks are purchased direct from pre-approved battery bank manufacturers. Battery banks are purchased for individual substation projects and for replacement of deteriorated existing banks throughout the system as needed. Lead acid battery banks are purchased as close to their required need date as possible.
What type of battery bank does JEA use?
JEA has standardized on lead acid type battery banks to supply this 125 volt DC requirement for its substations. There are two major types of battery banks used for substation applications; lead acid and nickel cadmium. The nickel cadmium battery banks are about twice the cost of lead acid for the same size bank.
