Title: Understanding IEC 61000-4-144: 2019: A Technical Article on Electromagnetic Compatibility and Its Testing

IEC 61000-4-144: 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 explanation of IEC 61000-4-144: 2019, its scope, and the testing process. We will also discuss the key features and benefits of this standard, including the immunity tests, test levels, and evaluation criteria.

What is IEC 61000-4-144: 2019?

IEC 61000-4-144: 2019 is an international standard that defines a set of conditions for simulating realistic electromagnetic environments. It provides guidelines for conducting electromagnetic interference (EMI) tests, including the use of immunity tests, test levels, and evaluation criteria.

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. By subjecting equipment to these tests, manufacturers can assess its performance and susceptibility to EMI.

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

Testing Process:

To ensure that equipment meets the requirements of IEC 61000-4-144: 2019, manufacturers must conduct EMI tests on their products. The testing process typically consists of the following steps:

Step 1: Conduct a risk assessment: Manufacturers must conduct a risk assessment to determine the potential sources of EMI in their equipment.

Step 2: Select the appropriate test: Based on the risk assessment, manufacturers must select the appropriate test for their equipment. The standard defines several immunity tests, including the anechoic test, the open circuit test, and the conducted test.

Step 3: Conduct the test: Manufacturers must conduct the chosen test on their equipment, following the guidelines provided in the standard.

Step 4: Analyze the results: Manufacturers must analyze the results of the test, including any measurements taken during the test.

Step 5: Evaluate the product: Manufacturers must evaluate their products based on the results of the tests, including any measurements taken during the test. They must also document their results in a report.

Conclusion:

IEC 61000-4-144: 2019 is an essential standard for ensuring the EMC of electrical and electronic equipment connected to the electric power network. By subjecting equipment to the tests defined in this standard, manufacturers can assess its performance and susceptibility to EMI. The standard provides guidelines for conducting immunity tests, test levels, and evaluation criteria.
