What is a substation battery system?

The primary role of the substation battery system is to provide a source of energy that is independent of the primary ac supply, so that in the event of the loss of the primary supply the substation control systems that require energy to operate can still do so safely.

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 big a flooded cell battery for a substation?

Now, let’s do some math and size a flooded cell, lead-acid battery for a substation. The battery will be rated 125V DC nominal and have an amp-hour capacity rated for an 8-hour rate of discharge. In most substations, the 8-hour rate of discharge is the standard.

Will a substation have a dual battery system?

Thus they will be dual but not 100% redundant. An extended outage of the battery charger on one bank while the other bank i

How should a substation be oriented?

The substation should be oriented so the lines to Des-Moines comes out of the the low side breaker and the lines to Cedar Falls comes out of the high side breaker. This will affect where the H-frames are located and which side of the substation will be the low side and which side will be the high side.
