6 FAQs about [How to replace the battery in the substation]

When should substation batteries be replaced?

Substation batteries are crucial to the overall reliability of the substation. If they have served for 20 to 25 years and have reached 80% to 90% of their capacity, it's recommended to replace them. It's not worth trying to extract the last bit of life from the batteries. Two ways to monitor the batteries 24/7 are:

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.

How to choose a battery for a substation?

all work using DC power. A battery that not only packs enough energy but also provides the discharge characteristics to operate substation equipment is needed. Specify batteries with enough amp-hour capacity to support the continuous load for 8 hours and momentary load (such as breaker and switch operation) for a minute or more.

How do you protect a substation battery?

There’s also the chance of an unqualified person ignoring the warning sign and entering the substation. So some sort of protective, ventilated enclosure is always recommended where the batteries are capable of coming in contact with personnel. Adequate illumination must also be provided around these battery banks.

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.

Do you need a battery room in a substation?

Since acid or alkaline liquids and vapours are toxic, a separate battery room is traditionally provided in the substation control building to house the battery banks. The room has to have adequate ventilation (possibly forced), an acid resistant concrete or tiled floor and sink unit with running water and eye wash facilities.
