What is IEC 61000-4-151:2019 ?

IEC 61000-4-151:2019 is an essential standard for evaluating the electromagnetic compatibility (EMC) of electrical and electronic equipment. It is developed by the International Electrotechnical Commission (IEC) and focuses on ensuring the immunity of devices from electromagnetic interference (EMI) caused by radio transmitters and other sources.

IEC 61000-4-13:2019, also known as "Electromagnetic compatibility (EMC) - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests, " is an international standard that outlines the testing and measurement techniques for EMC. 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 61000-4-13:2019 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 fields. 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 for IEC 61000-4-13:2019 consists of several steps, including:

Definition of the electromagnetic environment: The first step is to define the electromagnetic environment in which the equipment will be tested. This involves identifying the sources of electromagnetic interference, such as radio transmitters, and the characteristics of the electromagnetic field.

Configuration of the equipment: The next step is to configure the equipment to be tested, including the type and extent of the equipment, the frequency and duration of the test, and the expected level of interference.

Testing procedures: The testing procedures for IEC 61000-4-13:2019 include a number of different tests, including mains signalling, harmonic and interharmonics, and low frequency immunity tests. These tests are designed to simulate the electromagnetic environment and assess the performance and susceptibility of the equipment.

Data collection and analysis: After the testing is complete, the data collected from the tests is analyzed to determine the performance and immunity of the equipment. This data can be used to identify areas for improvement and to ensure that the equipment meets the requirements of the standard.

Conclusion

IEC 61000-4-151:2019 is an important standard for evaluating the EMC of electrical and electronic equipment. It provides a framework for testing and measuring the immunity of devices to electromagnetic interference caused by radio transmitters and other sources. By subjecting equipment to these tests, manufacturers can ensure that their products are capable of operating properly in the presence of electromagnetic interference and that they meet the requirements of the standard.
