What is IEC 61000-4-155:2019 ?

IEC 61000-4-155:2019 is an international standard that outlines the testing and measurement techniques used for electromagnetic compatibility (EMC). It is also known as the "Electromagnetic compatibility (EMC) - Part 4-155:2019," and it focuses on harmonics and interharmonics, which are disturbances caused by non-sinusoidal electrical waveforms that can affect the performance of electronic devices and systems connected to the electric power network.

IEC 61000-4-155:2019 provides guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference. The main purpose of the standard is to define a set of conditions that simulate realistic electromagnetic environments. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic fields.

The testing process for IEC 61000-4-155:2019 consists of several steps, including:

Test setup: The first step is to set up the testing environment, which includes the equipment to be tested, the frequency and power level of the test signal, and the test parameters.

Calibration: The next step is to calibrate the equipment to ensure that it is functioning properly and that the test parameters are set correctly.

Testing: The testing process begins with the equipment being subjected to the test signal. The test signal is generated using a test generator and is passed through the equipment. The equipment's performance is then measured and recorded.

Reporting: The final step is to report on the test results, including the equipment's performance, the test parameters, and any issues or concerns.

In conclusion, IEC 61000-4-155:2019 is an important international standard that outlines the testing and measurement techniques used for electromagnetic compatibility. It provides guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic fields, and ensure that they meet the necessary standards for the market.
