Title: IEC 61000-4-135:2019: A Technical Article on Electromagnetic Compatibility and Interference

Introduction:

IEC 61000-4-135:2019 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 focuses on harmonics and interharmonics, which are disturbances caused by non-sinusoidal electrical waveforms that can affect the performance of such equipment.

What is IEC 61000-4-135:2019?

IEC 61000-4-135:2019 is an international standard that relates to the testing and measurement techniques used for EMC. It specifically 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.

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 61000-4-1:2019

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 electromagnetic interference. 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 61000-4-1:2019, manufacturers must conduct the necessary testing. The testing process typically includes the following steps:

Step 1: Conduct a risk assessment to determine the likelihood of electromagnetic interference (EMI) affecting the equipment.

Step 2: Select the appropriate test method and specify the requirements for the test.

Step 3: Conduct the test in a controlled environment that simulates the electromagnetic environment of the equipment.

Step 4: Record the test results, including the equipment's performance level, the level of electromagnetic interference detected, and any necessary repairs or modifications.

Step 5: Evaluate the test results and determine whether the equipment meets the requirements of IEC 61000-4-1:2019.

Conclusion:

IEC 61000-4-135:2019 is an essential standard for ensuring the EMC of electrical and electronic equipment connected to the electric power network. By subjecting their products to the necessary tests, manufacturers can ensure that their equipment is compatible with the electromagnetic environment and operates without electromagnetic interference from radio transmitters or other sources. The testing process outlined in IEC 61000-4-1:2019 provides manufacturers with a structured and systematic approach to conducting the necessary tests and ensuring their products meet the requirements of the standard.
