WHAT IS AN ISO – INSULATION TEST?
An insulation test is an electrical examination conducted to verify the insulation integrity of an electrical device or installation. In this test, the insulation resistance between the live parts and non-live parts of the device is measured.
This is done by applying a high voltage to the parts to be tested, and the insulation resistance is measured. A high insulation resistance measurement indicates that the insulation is intact, and there are no undesired electrical leakage currents. Insulation testing is crucial to ensure the safety of electrical devices and minimize the risk of electric shocks or other electrical hazards.

HOW IS AN INSULATION TEST CONDUCTED?
Here are the basic steps to conduct an insulation test:
- Preparation:
Ensure that the device is turned off and disconnected from the power grid. Also, check whether the testing equipment is functioning properly and calibrated. - Connection of the Testing Equipment:
Connect the testing equipment to the test points of the device. Ensure that the connection is firm and secure. - Setting the Test Voltage:
Set the desired test voltage on the testing equipment. The test voltage depends on the specific requirements of the device or the standard being followed. - Conducting the Test:
Turn on the testing equipment and initiate the insulation test. The testing equipment generates a high voltage applied to the device or component. The duration of the test may vary based on requirements. - Assessment of the Result:
The measurement results are provided in ohms. There are various standards and regulations that specify the minimum values for insulation resistance that must be met.
During the complete execution, safety guidelines according to EN 50191 must be followed. It is crucial that the test is performed by trained personnel due to the use of high voltages that can lead to dangerous situations. Additionally, the lines or devices to be tested should be de-energized before the test to prevent accidents.
