BACKGROUND: Batteries are critical components of electrical transmission and distribution systems. When faults are detected, batteries provide a reliable source of auxiliary power to the protective relays, which operate circuit breakers. In addition, when station power is lost, batteries provide a consistent source of power to critical systems such as supervisory control and data acquisition (SCADA) and communication equipment, allowing operators to continue operating the system. RPU has standardized the use of vented lead acid -type battery banks to supply this 125 -volt DC requirement for the substations. These vented lead acid battery banks have proven to be very reliable and have low maintenance requirements and an average life span of 15 years.
