Objective: To ensure satisfactory circuit breaker life cycle performance research tasks in this project are designed to:
- Help utilities better understand circuit breaker operating stresses, underlying failure modes, and degradation rates
- Provide knowledge and guidelines for selection, application, procurement, maintenance, and condition assessment and testing

Novel SF6 Leak Sealing Techniques evaluates sealing materials and develops repair techniques for circuit breaker (CB) and gas insulated substations (GIS) that are:
-
Easy to apply, remove and reapply by utility personnel
-
Do not require specialized tools or clamps
-
Do not require de-pressurization
