This document is a Breaker Maintenance checklist form for an SPS2 type circuit breaker, associated with Gainesville Regional Utilities' (GRU) 138 KV Oil Breaker Replacements Project in Florida. The form provides a comprehensive maintenance inspection template for electrical circuit breakers, detailing multiple critical testing procedures including timing tests, travel tests, ductor measurements, megger testing, power factor testing, SF6 gas analysis, pressure switch settings verification, alarm checks, mechanical inspections, and general maintenance tasks.

The maintenance checklist includes specific technical parameters such as first trip timing (< 26ms), closing time (< 63ms), stroke measurement (110 mm), electrical resistance measurements (< 130 micro ohms), insulation resistance testing, SF6 gas purity requirements (> 97%), moisture levels (< 300 ppm), and pressure switch settings (operating pressure at 87 psi). The form allows for detailed documentation of test results across three separate poles, with space for recording serial number, breaker type, ambient temperature, and technician comments, supporting GRU's systematic approach to maintaining and replacing aging electrical infrastructure.
