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
Effectiveness Assessment of Circuit Breaker Online Monitoring and Diagnostic Testing provides guidance for nonintrusive monitoring and diagnostic tests to support condition-based maintenance for interrupter arcing and main contacts.
