What is a Insulation resistance tester?

An insulation resistance tester (also known as a megohmmeter) is a device used to assess the insulation condition of electrical equipment and wiring. It measures leakage current and insulation resistance to ensure the safety of electrical circuits and systems. This tool is essential for inspecting and maintaining power facilities and electronic devices. By applying a high voltage, it detects insulation faults and aging, helping to prevent accidents caused by leakage. Insulation testers come in a variety of models, from portable devices to larger industrial versions.

Application of Insulation resistance tester

✅Inspection of Distribution Panels
Used to verify the insulation condition of distribution panels in factories or buildings, preventing fires and equipment failures caused by leakage.
✅Maintenance of Electric Motors
Checks for degradation of coils and insulation within motors, ensuring efficient operation and extending lifespan.
✅Routine Check of High-Voltage Equipment
Verifies the insulation performance of high-voltage cables and transformers to ensure stable power supply.
✅Inspection of New Wiring Installations
Ensures new wiring in construction sites or facility upgrades is properly insulated.
