Title: Understanding IEC 61000-4-173:2019: A Technical Article on Electromagnetic Compatibility and Interference

Introduction:

IEC 61000-4-173:2019 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.

In this article, we will provide a technical overview of IEC 61000-4-173:2019, discussing its purpose, scope, and the testing process. We will also highlight the key features and requirements of this standard, including the immunity tests, test levels, and evaluation criteria.

Purpose and Scope of IEC 61000-4-173:2019:

IEC 61000-4-173:2019 is designed to define a set of conditions that simulate realistic electromagnetic environments. 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.

The primary purpose of IEC 61000-4-173:2019 is to ensure that equipment is capable of operating without being affected by electromagnetic interference (EMI) from radio transmitters or other sources. The standard provides guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference.
