What is IEC 61000-4-142: 2019 ?

Title: Understanding IEC 61000-4-142: 2019: A Technical Article on Electromagnetic Compatibility and Interference

IEC 61000-4-142: 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 defines a set of conditions that simulate realistic electromagnetic environments and subjects electrical and electronic equipment to tests to assess their performance and susceptibility to electromagnetic interference (EMI).

What is IEC 61000-4-142: 2019?

IEC 61000-4-142: 2019 is an international standard developed by the International Electrotechnical Commission (IEC) that focuses on the testing and measurement techniques used for EMC. The standard specifically relates to immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters or other sources.

The Purpose of IEC 61000-4-142: 2019

The main purpose of IEC 61000-4-142: 2019 is to define a set of conditions that simulate realistic electromagnetic environments and assess the performance and susceptibility of electrical and electronic equipment. 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 comply with the requirements of IEC 61000-4-142: 2019, manufacturers must conduct tests that simulate realistic electromagnetic environments. These tests typically include the use of equipment that is capable of emitting and receiving electromagnetic fields.

The standard defines four different test levels, each with distinct requirements for the equipment's performance and the level of interference it is allowed to receive. These test levels are:

* Level 1: Equipment that is not intended for use in the presence of electromagnetic interference.

* Level 2: Equipment that is intended for use in the presence of electromagnetic interference, but is not expected to perform well in the presence of significant interference.

* Level 3: Equipment that is intended for use in the presence of electromagnetic interference and is expected to perform well in the presence of significant interference.

* Level 4: Equipment that is intended for use in the presence of electromagnetic interference and is expected to perform well in the presence of significant interference, and also meets the requirements of IEC 61000-4-141: 2019 for immunity to electrical and electromagnetic interference.

Testing and Measurement Techniques:

To conduct the tests required by IEC 61000-4-142: 2019, manufacturers must use the appropriate testing and measurement techniques. These techniques include the use of equipment that is capable of emitting and receiving electromagnetic fields, and the use of software that is designed to simulate realistic electromagnetic environments.

The standard provides guidelines for conducting the tests, including the test equipment, the test procedures, and the data acquisition and analysis techniques. It also includes requirements for the equipment's performance and the level of interference it is allowed to receive.

Conclusion:

IEC 61000-4-142: 2019 is an essential standard for ensuring the EMC of electrical and electronic equipment connected to the electric power network. It defines a set of conditions that simulate realistic electromagnetic environments and subjects electrical and electronic equipment to tests to assess their performance and susceptibility to EMI. By subjecting electrical and electronic equipment to these tests, manufacturers can ensure that their products are capable of operating without being affected by electromagnetic interference from radio transmitters or other sources.
