COURSE OVERVIEW

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using our state-of-the-art simulators.
This course is designed to provide participants with a detailed and advanced overview of circuit breakers operation and maintenance. It covers the importance of circuit breakers in oil and gas electrical systems and its applications in substations, motors and generators; the classification and operating principles of air, SF₆, vacuum, and oil circuit breakers, arc interruption methods, current breaking capacity and tripping mechanisms; the electrical design, rating parameters and construction and components of circuit breakers; and interrupting medium and dielectric strength standards and applications.
Further, the course will also discuss the control circuits and interlocks covering typical AC/DC control schemes, interlocking mechanisms, control wiring schematics and testing control circuits; the protection schemes in petroleum plants; the breaker operating sequences and breaker failures and protection; the coordination with relays and fuses and breaker communication and remote operation; the preventive maintenance philosophy and visual and mechanical inspection; the electrical testing of circuit breakers, diagnostic techniques and testing equipment and setup; and maintaining different breaker types and the common operational issues.
During this interactive course, participants will learn the root cause analysis (RCA) for failures, corrective and predictive actions and breaker replacement and retrofit strategy; the safety practices during troubleshooting covering lockout-tagout (LOTO), arc flash risk assessment, PPE requirements and isolation procedures; the breaker performance, digitalization and smart breakers and environmental and regulatory compliance; the advanced arc quenching technologies; and the field application in petroleum operations.
