An example battery bank from a substation tour is shown in Figure 1. To insure proper operation, substation batteries need to be inspected and maintained. Items to be inspected monthly include:
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
