Theoretical Foundation High Voltage Safety & Switching

This course is designed to instruct electrical personnel in the safe working techniques for offshore and onshore industrial high-voltage applications.

Delegates attending this course should have knowledge of basic electrical practice and theory. Technical training in a relevant electrical/ electronic discipline (AAS) or equivalent two years of practical electrical experience.

The course covers the IEC & NEC standards for HV switching, electrical isolations, and flash protection boundaries per the NFPA 70E 2020. Our new power generation and distribution simulator instructs technicians in the start-up and troubleshooting of offshore power systems, including fundamental system principles and dynamics, bus loading management, distribution to lower voltage electrical networks, HV electrical cabling & stress relief concepts, and other associated electrical applications

The following topics wil l be covered during the course: • Electrical Hazards & Electrical Safety • Safe work practices (LOTO, arc flash, PPE) • Case studies of incidents and lessons learned • Legislations & Standards (Singapore & UK) • Legal responsibilities, audits, and compliance examples • Electric Distribution Systems o System layout, components, and protection basics o Fault level concepts and earthing methods • Generator Synchronization Requirements o Conditions, synchronizers, islanding, black start concepts • Introduction to HV Switchgear o Types (vacuum, SF₆), functions, safety consideration • Introduction to LV Switchgear o Breaker types, ratings, coordination • HV vs. LV comparisons • Learning Outcomes: o Explain synchronization principles o Identify key differences in HV/LV gear • Switching Operations & Planning o Switching schedules, permits, and LOTO o Theoretical walk-through of isolation/re-energization • Group activity: design a theoretical switching plan • Interlocks and operational controls (theoretical overview)
