HV/LV electrical systems require special application of maintenance, repair, test, and safety procedures. Personnel must be trained in special precautions to ensure both personnel and workplace safety. OSHA requires training for all qualified employees performing operations or maintenance work, or who have access to electrical power generation, transmission and distribution installations. This course will provide authorization certification to work in LV and HV electrical systems for operation and maintenance team.
The course covers the knowledge and skills needed to safely work with energized HV/LV electric power systems. It covers electrical safety requirements including the principles and procedures for the safe operation and maintenance of such systems. Insulated hand tools, proper grounding procedures, proper protective clothing, and thorough job-planning procedures are covered throughout the course. Properties of electric charge, energy, electric potential, dielectric stress, capacitive and inductive coupling, and material behavior in electromagnetic fields are discussed.
The effects of electrical energy on humans and various protection concepts are addressed, as are basic first aid practices. Differential protection schemes, insulation materials, Equi-potential grounding, live-line tools, and isolation techniques are covered from both the technical and practical perspectives.
Various OSHA, IEEE, European and NFPA safety procedures are reviewed. Group exercises include the development of safe-work protocols, use of logout/tagout (LOTO), maintenance task rehearsal, and equipment preparation. Fault current, arc-flash hazards, and proper PPE selection are studied. Other technical topics covered include insulation testing, corona detection by ultrasonic and RF detectors, and signature analysis using an infrared imager.
Successful course participants who attend the course and pass competency exam, will be certified to work on high voltage electrical power systems. Course participants are introduced to the hazards of electrical work and the philosophies of preventing accident and minimizing outage time due to improper safety or work practices. Also included as part of the curriculum are study materials participants may use at their own pace to continue their learning experience. This course addresses OSHA training requirements established in OSHA 29 CFR 1910.269.
