Fundamentals of Switchgear: SF6, Medium Voltage, and Vacuum Circuit Breakers (VCB)

The Fundamentals of Switchgear Training Course offers a detailed understanding of the equipment that forms the backbone of electrical distribution networks. As power systems evolve, the need for safe, efficient, and modern switchgear becomes increasingly important. This training equips participants with a thorough grasp of the technologies used in today’s installations, including SF₆ switchgear, medium voltage assemblies and vacuum circuit breakers (VCBs), all of which play a pivotal role in protecting assets, minimizing downtime and ensuring operational continuity.

The course focuses on how switchgear enables isolation, control and protection of electrical infrastructure, and why each technology—SF₆, MV switchgear and VCBs—has become essential in industrial, utility and commercial environments. Participants explore construction features, functional characteristics and operating principles, while gaining clarity on failure modes, maintenance practices and safe operating procedures. Real-world insights highlight environmental considerations, including the global shift toward low-emission alternatives to SF₆ and the growing adoption of vacuum-based technologies.

By the end of the course, participants will be prepared to make informed decisions regarding the selection, application, and maintenance of switchgear systems that align with modern safety standards and operational expectations.

Participants will strengthen their capability to manage switchgear technologies used in contemporary electrical networks and apply best practices for safe, reliable operation.

They will be able to:

• Understand essential concepts, operating principles and components of switchgear
• Explain the functionality and application of SF₆, medium voltage and VCB technologies
• Differentiate between switchgear types and select appropriate solutions for specific environments
• Perform fundamental inspection, maintenance and troubleshooting tasks
• Apply recognised electrical safety practices when working with switchgear systems
