In this video I will show you how to test insulation resistance for electrical installations or electric motors. A megger is used as insulation resistance tester. An industrial motor should have high insulation resistance between winding and its core or body. If a motor have broken resistance between winding and core and motor body. Also a megger or insulation resistance is used to measure resistance for cables and other electrical components. Understanding megger testing is a must for an electrical engineer or an industrial technician or electrician. Insulation resistance testing is a must have skill for electrical personnel in industry.
