What is insulation tester?
An insulation tester, also known as a megohmmeter or insulation resistance tester, is a device used to measure the resistance of electrical insulation. It applies a high DC voltage to the insulation and measures the resulting leakage current, calculating and displaying the insulation resistance in megohms (MΩ). This test helps identify insulation degradation or damage that could lead to electrical failures, short circuits, or safety hazards. Common uses include testing the insulation of cables, motors, transformers, and other electrical equipment to ensure it meets safety standards and prevent equipment failures.
