What is IEC EN 61000-4-19?

IEC EN 61000-4-19 is an international standard developed by the International Electrotechnical Commission (IEC) that addresses the testing and measurement techniques for electrical and electronic equipment in relation to electromagnetic compatibility (EMC). This standard specifically focuses on the measurement of conducted disturbances induced by power and signal lines in the frequency range of 0 Hz to 150 kHz.

The Purpose of IEC EN 61000-4-19

The main purpose of IEC EN 61000-4-19 is to establish uniform testing procedures and guidelines for evaluating the impact of conducted disturbances on electrical and electronic equipment. By defining standardized measurement methods, this standard ensures that equipment manufacturers and testers can assess the susceptibility of devices to such disturbances in a consistent and reliable manner.

Key Elements of IEC EN 61000-4-19

This standard outlines various aspects related to the measurement of conducted disturbances, including test setups, measurement procedures, and assessment criteria. It provides guidelines for both continuous and transient disturbances induced by power and signal lines, as well as detailed instructions for setting up and calibrating the necessary measuring equipment.

Additionally, IEC EN 61000-4-19 defines specific test methods for evaluating the immunity of equipment to voltage dips, short interruptions, and voltage variations in the low-frequency range. These tests ensure that devices are capable of withstanding fluctuations or interruptions in power supply without malfunctions or damage.

Benefits and Applications of IEC EN 61000-4-19

Compliance with IEC EN 61000-4-19 is essential for manufacturers of electrical and electronic equipment who want to ensure the reliability and performance of their products. By adhering to this standard, manufacturers can:

Assess and improve the immunity of their devices to conducted disturbances

Enhance the overall electromagnetic compatibility of their products

Meet regulatory requirements and certifications related to EMC

Furthermore, the application of IEC EN 61000-4-19 extends beyond equipment manufacturers. Testing laboratories, certification bodies, and regulatory authorities also rely on this standard to validate equipment performance and compliance, ensuring a safe and harmonized electromagnetic environment for various industries.

In conclusion, IEC EN 61000-4-19 plays a crucial role in evaluating the impact of conducted disturbances on electrical and electronic equipment. Its standardized measurement procedures and guidelines enable manufacturers to enhance device immunity, improve electromagnetic compatibility, and meet regulatory requirements, ultimately contributing to a more reliable and efficient operation of electronic systems in various sectors.
