Title: Understanding IEC 61000-4-126:2019: A Technical Article on Electromagnetic Compatibility and Its Importance

IEC 61000-4-126:2019 is an essential standard for ensuring the electromagnetic compatibility (EMC) of electrical and electronic equipment ( equipment) connected to the electric power network. This standard was developed by the International Electrotechnical Commission (IEC) and is widely recognized and adopted by manufacturers and regulatory authorities around the world.

What is IEC 61000-4-126:2019?

IEC 61000-4-126:2019 is a set of conditions that simulate realistic electromagnetic environments. 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. The standard 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.

What is IEC 61000-4-1:2019?

IEC 61000-4-1:2019 is an important international standard that relates to the testing and measurement techniques used for EMC. This standard specifically focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters. 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.

The Purpose of IEC 61000-4-126:2019

The main purpose of the IEC 61000-4-126:2019 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 standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from radio transmitters or other sources.

The Testing Process:

To ensure that their products meet the requirements of IEC 61000-4-126:2019, manufacturers must conduct a series of tests to verify the electromagnetic compatibility of their equipment. These tests typically include the anechoic search, a method of measuring the response of equipment to a changing electromagnetic environment, and the measurement of immunity, which is the ability of equipment to withstand electromagnetic interference from a radio transmitter.

Conclusion:

IEC 61000-4-126:2019 is an essential standard for ensuring the electromagnetic compatibility of electrical and electronic equipment. By subjecting their products to these tests, manufacturers can assess their performance and susceptibility to electromagnetic interference from radio transmitters or other sources. The standard provides guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices are capable of operating without being affected by electromagnetic interference. By adopting this standard, manufacturers can ensure that their products are reliable and perform as expected in the presence of electromagnetic interference.
