Description
This 4-day, in-person course combines the expertise of DILO and Doble. Circuit breaker operational testing and management of SF6 gas are key aspects in maintaining circuit breakers to help ensure reliable operation.
The first two days of the training program focus on SF6 gas theory and practical equipment demonstrations. The aim is to provide technicians with the necessary knowledge to optimize SF6 gas handling practices, safety procedures, and regulations/reporting. The theoretical portion covers the characteristics and properties of SF6 gas, the differences between virgin and reconditioned gas, an in-depth analysis of contaminants found in SF6 gas, gas analysis theory, leak detection methods, zero-emission SF6 gas handling theory, and up-to-date regulatory and reporting information. During the practical, hands-on portion, learners will witness demonstrations of emission-free SF6 gas handling (recovery, evacuation, and filling), along with gas analysis and leak detection. Attendees will have the opportunity to handle equipment and ask questions in an intimate setting.
In partnership with Doble, the second 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.

SURVEY
Please take a few moments to fill out the pre-course survey in DILO Academy. This will help instructors learn what equipment you are currently working with and if there is anything specific you want to focus on so we can do our best to tailor the course to the unique requirements of each learner.
REGISTRATION
Please bring a valid driver's license or other form of government I.D.
DRESS CODE & SAFETY REQUIREMENTS
This course includes both theoretical and hands‐on components. Attendees are required to wear appropriate safety gear (gloves, steel toed boots, and safety glasses) during the hands‐on portions of the course. It is highly recommended that attendees bring their own safety gear; however, DILO will provide gear to those who are unable to bring their own. The dress code for this course is casual to business casual. Dressing in layers is recommended.
F&B
Light morning refreshments, lunch, coffee, soft drinks, and juice will be provided on each training day. Please be sure to advise us of any dietary restrictions in advance by utilizing the dietary restriction section in the course registration or by contacting us at sales@dilo.com.
