Power System Reliability: Circuit Breaker Operation & Maintenance
Sector:
Power & Electricity – T&D/Systems
Technical Focus Area:
Electrical Power Systems (ELEC)
About the Course
Modern electrical plants depend on circuit breakers, fused switches, and switchgear to safely control, isolate, and protect equipment under normal and fault conditions. This hands-on course blends grounded theory with field-ready methods to help participants install, operate, and maintain LV–MV–HV switchgear with confidence. You will learn device selection and nameplate interpretation, fault-level implications, coordination with CTs/VTs and protection schemes, and the operating principles of air, vacuum, and SF6 breakers. The program develops proficiency in diagnostics and condition assessment using DVMs, meggers, oscilloscopes, IR thermography, and cable fault locators, and translates results into targeted maintenance actions. Emphasis is placed on safety leadership—lockout/tagout, step-and-touch potential, arc-flash awareness, and permit-to-work—plus compliance with NEC/IEC guidance. You will also practice documentation, job planning, and failure analysis to reduce downtime, extend asset life, and meet reliability and regulatory goals.
Objectives
- Explain operating principles and duty of common breaker and switchgear types (air, vacuum, SF6)
- Perform fault-level awareness, basic calculations, and interpret system implications
- Apply structured troubleshooting with test instruments and condition indicators
- Conduct inspections, testing, and certification to improve reliability and compliance
- Interpret single-line diagrams, control schematics, wiring lists, and nameplate data
- Implement LOTO, safe working distances, and step-/touch-potential controls
- Plan and document O&M tasks to reduce repeat failures and downtime
- Align maintenance practices with NEC/IEC guidance and site procedures
