Leakage Current Test
WHAT IS A LEAKAGE CURRENT TEST?
A leakage current test is a procedure for testing the leakage current of an electrical device or system. The leakage current is the current that flows through unwanted paths, such as through the insulation or via the protective earth conductor. The leakage current test measures the current that flows through these unwanted paths to ensure that it is within safe limits. A high leakage current measurement can indicate faulty insulation or other problems that can lead to an increased risk of electric shock. Proper leakage current testing is important to ensure the safety of people using the electrical device and to ensure that it complies with applicable safety standards.
HOW IS A LEAKAGE CURRENT MEASUREMENT CARRIED OUT?
Here are the basic steps for carrying out a leakage current measurement:
- Standards: Analysis of which standard and which specified diagrams must be used for testing.
- 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 / test current: Set the desired test voltage and the maximum test current on the test device. The test voltage / test current depends on the specific requirements of the device or the standard to be tested.
- Carry out the test: Switch on the test device and start the leakage current test.
- Evaluation of the result: The measurement results are given in amperes. There are various standards and regulations that specify the maximum values for the leakage current that must be adhered to in order to ensure safety.
The leakage current measurement is an active test in which the test object is tested when it is switched on.
