WHAT IS AN INSULATION RESISTANCE TEST?
An insulation resistance test is a procedure to verify the insulation resistance of an electrical device or installation. Insulation resistance is the resistance to the flow of current through unintended paths, such as through insulation or the protective conductor. During the insulation resistance test, the current flowing through these unintended paths is measured to ensure that it is within safe limits. A high insulation resistance measurement may indicate faulty insulation or other issues that could lead to an increased risk of electric shocks. Proper insulation resistance testing is crucial to ensure the safety of individuals using the electrical device and to confirm that it complies with applicable safety standards.

HOW IS AN INSULATION RESISTANCE TEST CONDUCTED?
An insulation resistance test is a procedure to verify the insulation resistance of an electrical device or installation. Insulation resistance is the resistance to the flow of current through unintended paths, such as through insulation or the protective conductor. During the insulation resistance test, the current flowing through these unintended paths is measured to ensure that it is within safe limits. Here are the basic steps to conduct an insulation resistance test:
- Standards: Analyze which standard and specified diagrams need to be followed for the test.
- Preparation: Ensure that the device is turned off and disconnected from the power supply. Also, check if the test equipment is functioning properly and calibrated.
- Connection of the test equipment: Connect the test equipment to the device’s terminals to be tested. Ensure that the connection is tight and secure.
- Setting the test voltage / test current: Set the desired test voltage and maximum test current on the test equipment. The test voltage / test current depends on the specific requirements of the device or the standard being tested.
- Performing the test: Turn on the test equipment and initiate the insulation resistance test.
- Evaluation of the result: The measurement results are given in amperes. There are various standards and regulations that specify maximum values for insulation resistance to ensure safety.
The insulation resistance test is an active test where the test object is tested in the energized state.
