Cable meggering is a vital testing procedure used to assess the insulation resistance of electrical cables, ensuring their safety and reliability. It involves applying a high DC voltage, typically using a megohmmeter (commonly known as a "megger"), to detect any insulation breakdown or leakage currents. This test helps identify potential faults, moisture ingress, or aging-related deterioration in cable insulation. Regular megger testing is essential in preventing electrical failures, short circuits, or fire hazards. It is widely used during cable installation, routine maintenance, and troubleshooting. Cable meggering ensures compliance with safety standards and contributes to the long-term performance of electrical systems.
