What is IEC 61000-4-152: 2019 ?

Title: Understanding IEC 61000-4-152: 2019: A Technical Article on Electromagnetic Compatibility and Interference

Introduction:

IEC 61000-4-152: 2019 is an essential standard for ensuring the electromagnetic compatibility (EMC) of electrical and electronic equipment ( equipment) connected to the electric power network. This international standard. also known as "Electromagnetic compatibility - Part 4-152: 2019. " is 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 electronic devices and systems.

In this article. we will delve into the details of IEC 61000-4-152: 2019. explaining its purpose. the testing process. and the criteria for evaluating the performance of equipment.

Purpose of IEC 61000-4-152: 2019:

The primary purpose of IEC 61000-4-152: 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 interference from radio transmitters or other sources. The standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from these sources.

The Testing Process:

IEC 61000-4-152: 2019 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 standard defines four test procedures. which are as follows:

Test procedure 1: "Receiver device"

This test procedure evaluates the performance of a receiver device in the presence of electromagnetic interference from a transmitter device. The transmitter device is typically a radio transmitter. and the receiver device is a device designed to detect and measure the electromagnetic interference.

Test procedure 2: "Transmitter device"

This test procedure evaluates the performance of a transmitter device in the presence of electromagnetic interference from a receiver device. The transmitter device is typically a radio transmitter. and the receiver device is a device designed to detect and measure the electromagnetic interference.

Test procedure 3: "Critical reflection coefficient (CRC) measurement"

This test procedure evaluates the performance of a device in the presence of electromagnetic interference and also measures the CRC.

Test procedure 4: "Immunity measurement"

This test procedure evaluates the performance of a device in the presence of electromagnetic interference from a transmitter device with a known frequency and amplitude.

Evaluation Criteria:

To ensure that products are compliant with the requirements of IEC 61000-4-152: 2019. manufacturers must demonstrate that their products meet the relevant criteria. These criteria are defined in the standard. which includes requirements for the design. testing. and documentation of electrical and electronic equipment.

Conclusion:

IEC 61000-4-152: 2019 is an essential standard for ensuring the electromagnetic compatibility of electrical and electronic equipment. By subjecting electrical and electronic equipment to the tests defined in this standard. manufacturers can assess the performance and susceptibility of their products to electromagnetic interference from radio transmitters or other sources. The standard provides guidelines for conducting the tests. test levels. and evaluation criteria to ensure that products are capable of operating without being affected by electromagnetic interference from these sources.
