EE1156 : Electrical Isolation and De-Isolation Requirements for Electrical Switchgears

 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 up-to-date overview of Electrical Isolation and De-Isolation Requirements for Electrical Switchgears. It covers the electrical isolation and de-isolation, electrical switchgears, energy sources and isolation requirements and standards and legal framework; the purpose and importance of risk assessments, risk assessment process, hazard identification specific to switchgears and risk control measures; the lockout/tagout (LOTO) principles, isolation devices in switchgears and step-by-step isolation process; and the de-isolation process and testing for dead (proving dead). Further the course will also discuss the personal protective equipment (PPE) for isolation tasks and safe access to electrical equipment; the safety precautions during isolation, human factors in isolation activities, documentation and isolation registers; the coordination of isolation in multi-discipline environments; the emergency situations during isolation and supervisor and authorized person roles; the isolation in low, medium and high voltage systems; the interlocking schemes and safety interlocks; and the common failures and near misses in isolation activities and permit to work (PTW) integration with isolation. 

During this interactive course, participants will learn the inspection and maintenance of isolation equipment; the isolation during maintenance and repair activities and isolation procedure; the inspection checklists, documentation, corrective actions and follow-up; the external workforce, responsibilities during isolation and communication and supervision requirements; the isolation procedures and breaches in isolation; and the immediate corrective action steps, escalation procedures and post-incident review.
