An Insulation Tester is a specialized electrical device used to measure the insulation resistance of electrical systems and equipment. It helps ensure that insulation materials are functioning properly, preventing electrical leaks that could lead to short circuits or equipment failure. By applying a high voltage to the insulation, the tester can identify weaknesses or breakdowns in the insulation. These testers are commonly used in various industries, including construction and maintenance, to ensure safety and compliance with electrical standards. Regular testing with an Insulation Tester can help maintain the integrity of electrical systems, protecting both equipment and personnel from potential hazards.
