Insulation resistance testing is important in various applications, including:
- Electrical Equipment Testing: Insulation resistance testing is performed on motors, generators, transformers, cables, switchgear, and other electrical equipment to ensure the integrity of the insulation and identify potential issues like insulation breakdown, moisture ingress, or degradation.
- Preventive Maintenance: Regular insulation resistance testing is part of preventive maintenance programs to detect insulation deterioration, insulation breakdown, or insulation-related faults. It helps in scheduling maintenance activities and avoiding unexpected equipment failures.
- Commissioning and Acceptance Testing: Insulation resistance testing is conducted during the commissioning of new electrical systems or equipment to verify their insulation integrity and compliance with specifications.
- Troubleshooting: When investigating electrical faults or malfunctions, insulation resistance testing can help identify insulation-related issues, such as short circuits, ground faults, or insulation breakdown caused by environmental factors or aging.
