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

Switchgear Battery Sizing by Hand

Since the momentary load on a switchgear battery bank is much higher than the continuous load, the required 1-minute (peak) ampere rate typically determines the battery cell type. However the Ampere-hour rate should also be checked. The battery cell type that meets the worst-case condition between the two should be selected.

Teaching Substation Battery Testing to Undergraduates

TY - CPAPER AB - Battery banks are crucial for the proper operation of an electrical power substation. When station service power is lost, the battery bank must power 1) the tripping and closing of circuit breakers, 2) all of the protective relays, 3) all indicators and annunciators, and 4) the remaining auxiliary equipment.

What is the function of battery bank in a substation?
