Title: Understanding IEC 61000-4-157:2019: A Technical Article on Electromagnetic Compatibility and Interference

Introduction:

IEC 61000-4-157:2019 is an essential standard for evaluating the electromagnetic compatibility (EMC) of electrical and electronic equipment. This international standard, also known as "Electromagnetic compatibility - Part 4-157:2019, " is developed by the International Electrotechnical Commission (IEC) and focuses on ensuring the proper functioning of devices in the presence of electromagnetic interference (EMI) from various sources.

What is IEC 61000-4-13:2019?

IEC 61000-4-13:2019, 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, " is a crucial standard for evaluating the EMC of electrical and electronic equipment. This standard, which is based on IEC 61000-4-13:2019, 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 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 EMI.

The Purpose of IEC 61000-4-1:2019

The main purpose of the IEC 61000-4-1:2019 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 EMI from radio transmitters or other sources. The standard aims to ensure that products are capable of operating without being affected by EMI.

The Testing Process

To evaluate the EMC of a device, manufacturers must conduct various tests, including those related to IEC 61000-4-13:2019 and IEC 61000-4-1:2019. These tests typically involve subjecting the device to various electromagnetic fields and measuring the device's performance in the presence of those fields.

The standard defines a set of requirements for conducting the tests, including the frequency and amplitude of the electromagnetic fields, the duration of the exposure, and the testing equipment. The tests are typically conducted in an anechoic chamber or a controlled environment that simulates real-world electromagnetic interference.

Conclusion

IEC 61000-4-157:2019 is an essential standard for evaluating the EMC of electrical and electronic equipment. This international standard, which is based on IEC 61000-4-13:2019, 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. By subjecting devices to these tests, manufacturers can ensure that their products are capable of operating without being affected by EMI from radio transmitters or other sources..
