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.
