SF6 Handling and Circuit Breaker Testing Training

Management of SF6 gas and Circuit breaker operational testing are key aspects in maintaining circuit breakers to help ensure reliable operation. This interactive 4-day course focuses on theoretical background with practical field experience to provide technicians with vital knowledge for optimizing circuit breaker reliability. Upon successful completion, attendees will be able to earn up to 3.2 CEUs or 32 Professional Development Hours.

In partnership with Doble, the first two days will cover circuit breaker testing. Moving parts on circuit breakers wear, alignments and clearances change and critical functions can be negatively affected. Tests made with circuit breaker testers reveal these and other changes, in advance of a failure, which could render the equipment inoperable and cause damage to the electrical power system. An introduction of various mechanism types, interrupters and testing methodologies will be discussed. For each test, there will be an in-depth discussion of each measurement, setup and test methodology, and acceptance criteria. A Vanguard specialist will provide training to decipher and review apparatus test results so that they are clear and easy to understand. Test results will be used for reporting and maintenance purposes and used for historical data samples to improve maintenance schedules.

The second two days will focus on SF6 gas handling fundamentals including theoretical and hands on training pertaining to safety, gas handling equipment and tooling, gas analysis, transportation, regulations and reporting. Test results will be used for reporting and maintenance purposes and used for historical data samples to improve maintenance schedules.
