Title: Understanding IEC 61000-4-128: 2019: A Technical Article on Electromagnetic Compatibility and Interference

IEC 61000-4-128: 2019 is an essential standard for evaluating the electromagnetic compatibility (EMC) of electrical and electronic equipment. This international standard 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. In this article, we will delve into the details of IEC 61000-4-128: 2019, including its scope, purpose, and testing process.

What is IEC 61000-4-128: 2019?

IEC 61000-4-128: 2019, also known as "Electromagnetic compatibility (EMC) - Part 4-128: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests, " is an international standard developed by the IEC. The standard aims 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 (EMI) from various sources.

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 various sources. The standard aims to ensure that products are capable of operating without being affected by EMI from radio transmitters or other sources.

The Testing Process

To evaluate the EMC performance of a device, the manufacturer must conduct a series of tests according to the guidelines outlined in IEC 61000-4-1: 201These tests typically include the following steps:

Step 1: Electromagnetic(EMC) Simulator

The first step in the testing process is to use an EMC simulator to generate simulated EMFs that may affect the device.

Step 2: Equipment configuration

The second step is to configure the device for testing, including setting the input and output frequencies, the power level, and any other relevant settings.

Step 3: Testing

The third step is to conduct the actual testing, which typically involves subjecting the device to the simulated EMFs generated by the EMC simulator.

Step 4: Reporting

The fourth step is to report the results of the testing, including the device's performance, any issues observed, and any necessary repairs or modifications.

Conclusion:

IEC 61000-4-128: 2019 is an essential standard for evaluating the EMC of electrical and electronic equipment. By subjecting devices to tests that simulate realistic electromagnetic environments, manufacturers can ensure that their products are capable of operating without being affected by EMI from various sources. The testing process outlined in IEC 61000-4-1: 2019 provides manufacturers with a standardized method for evaluating the EMC performance of their products.
