Substation Battery, Cell and Charger Replacement - Videos and Related Books
The key components of a DC control system include the battery, the individual cells in the battery, and the battery charger. As these components age, or as load requirements change, it is sometimes necessary to replace components to ensure that the control system fulfills its functions. Because these tasks are a common part of DC system maintenance, substation personnel need to be familiar with how they are carried out.This 32-minute video describes general procedures associated with the replacement of substation batteries, battery cells, and battery chargers.
