Cable meggering is a testing process used to assess the insulation resistance of electrical cables to ensure their safety and reliability. Using a megger (insulation resistance tester), a high voltage is applied between the cable conductors and ground to detect any leakage current. This test helps identify insulation deterioration, moisture ingress, or potential faults that could lead to short circuits or equipment failure. Regular meggering is crucial during installation, maintenance, and troubleshooting. It ensures compliance with electrical safety standards, extends cable life, and prevents unexpected breakdowns. Proper documentation of test results also aids in predictive maintenance and risk management.
