Advanced Electrical Maintenance

Advanced Electrical Maintenance

Electrical Maintenance and Testing of electric power systems is essential to the safe operation of any electrical system, regardless of its size, type or industry. Electrical worker inexperience and poor electrical maintenance planning will inevitably result in costly equipment failure and downtime.

This intense two-day Advanced Electrical Maintenance Training course provides invaluable information to anyone who wishes to know and understand the role of electrical maintenance standards, programs and procedures for the optimal maintenance of electric power systems. The importance of planning, programming and implementing electrical maintenance practices will be emphasized. This course also deals with safety considerations involved in electrical maintenance procedures for all the components of any electrical system. This will be an interactive forum where the instructor will lead the discussion between students so to maximze the educational experience.
