Training course length is customizable based on your needs.

The failure of electrical insulation systems is one of the leading causes of equipment faults and electrical fires. The ability to recognize possible insulation breakdown and take timely corrective actions can protect both the equipment and the people in a facility. This seminar will use lectures, slides, case history examinations, and hands-on demonstration to provide the greatest possible exposure to electrical insulation system testing that can be achieved in one day.

Anyone who works on or near power generation, transmission, or distribution systems should attend this course. Additionally, supervisors, managers, safety personnel, and those responsible for ensuring a safe work environment should attend this course.
