Insulation Resistance Measurement
WHAT IS AN INSULATION TEST?
An insulation test (ISO test) is an electrical test that is carried out to check the insulation integrity of an electrical device or electrical system. During this test, the insulation resistance between the live parts and the non-current-carrying parts of the device is measured.
This is done by applying a high voltage to the parts to be tested and measuring the insulation resistance.A high insulation resistance measurement indicates that the insulation is intact and that there are no unwanted electrical leakage currents. An insulation test is important to ensure the safety of electrical devices and to minimise the risk of electric shocks or other electrical hazards.
HOW IS AN INSULATION TEST CARRIED OUT?
Here are the basic steps for carrying out an insulation test:
- Preparation: Make sure that the device is switched off and disconnected from the power supply. Also check that the tester is working properly and is calibrated.
- Connecting the test device: Connect the test device to the device connections to be tested. Ensure that the connection is firm and secure.
- Setting the test voltage: Set the desired test voltage on the test device. The test voltage depends on the specific requirements of the device or the standard to be tested.
- Performing the test: Switch on the tester and start the insulation test. The tester generates a high voltage which is applied to the device or component. The test duration may vary depending on the requirements.
- Evaluation of the result: The measurement results are given in ohms. There are various standards and regulations that specify the minimum values that must be observed for the insulation resistance.
The safety guidelines in accordance with EN 50191 must be observed throughout the entire procedure. It is important that the test is carried out by trained personnel, as high voltages are used and this can lead to dangerous situations. In addition, the cables or devices to be tested should be de-energised before the test in order to avoid accidents.
