This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

 

High voltage electrical systems require the special application of maintenance, repair, test, and safety procedures. Personnel must be trained in special precautions to ensure both personnel and workplace safety. IEC specifies essential requirements regarding protection against electric shock of persons and livestock. It deals also with the application and co-ordination of these requirements in relation to external influences, give also the various limits of the effects of 50 Hz alternating current on humans and define 4 main risk zones, and IEC application to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage. 

 

OSHA requires training for all qualified employees performing operations or maintenance work, or who have access to electrical power generation, transmission and distribution installations as well as HSE personnel who are in charge of the safety and health of the employees, public and facilities. 

 

Various IEC, OSHA, IEEE, European and NFPA safety procedures are reviewed. In this interactive course, group exercises include the development of safe-work protocols, use of lockout/tagout (LOTO), maintenance task rehearsal, and equipment preparation. Calculations of fault current, arc-flash hazards, and proper PPE selection are studied. Other technical topics covered include insulation testing (IR/PI/DAR/DD), four-wire Kelvin low-resistance testing, corona detection by ultrasonic and RF detectors, and signature analysis using an infrared imager. 

 

 

This course is designed to provide participants with a detailed and an up-to-date overview of HV electrical safety. It covers the HV equipment; testing and commissioning; the electrical hazards and safety management; the de-energized and energized work; and the confined space and personnel protection.
