Title: IEC 61000-4-132:2019: A Technical Article on Electromagnetic Compatibility and Interference

Introduction

IEC 61000-4-132:2019 is an essential standard for ensuring the electromagnetic compatibility (EMC) of electrical and electronic equipment (1) connected to the electric power network. This international standard, also known as "Electromagnetic compatibility - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests," focuses on harmonics and interharmonics, which are disturbances caused by non-sinusoidal electrical waveforms that can affect the performance of electronic devices and systems (2).

What is IEC 61000-4-132:2019?

IEC 61000-4-132:2019 is an international standard developed by the International Electrotechnical Commission (IEC) that defines a set of conditions for simulating realistic electromagnetic environments. The standard focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters or other sources. 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 (3).

What is IEC 61000-4-1:2019?

IEC 61000-4-1:2019 is an important international standard related 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 (4).

The Purpose of IEC 61000-4-132:2019

The main purpose of the IEC 61000-4-132:2019 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 interference from radio transmitters or other sources. The standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from radio transmitters or other sources (5).

Testing Process

To ensure that their products comply with the requirements of IEC 61000-4-132:2019, manufacturers must conduct electromagnetic interference (EMI) testing on their equipment. The testing process typically includes the following steps:

Step 1: Conduct a risk assessment to identify potential sources of electromagnetic interference (EMI) in the product design or environment.

Step 2: Select the appropriate EMI testing method based on the product's requirements and the environment in which it will be used.

Step 3: Conduct the EMI testing according to the testing method.

Step 4: Analyze the data collected during the testing to identify any potential EMI sources or areas for improvement.

Step 5: Implement corrective actions to eliminate or reduce EMI sources.

Step 6: Repeat the testing to ensure that the improvements have been made.

Conclusion

IEC 61000-4-132:2019 is an essential standard for ensuring the EMC of electrical and electronic equipment connected to the electric power network. IEC 61000-4-1:2019 is a standard that focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by 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.
