Electrical relays. Part 22: Electrical disturbance tests for measuring relays and protection equipment. 1 MHz burst disturbance tests

This standard outlines specific test methodologies designed to evaluate the electromagnetic compatibility of measurement relays and protection devices. It focuses on the application of burst disturbance stimuli at a frequency of 1 MHz, which serves as a critical assessment tool to ensure the reliability of such equipment in environments subject to high-frequency electrical interference. The defined procedures detail how devices should be exposed to these transient signals and how their performance must be observed during and after the event. By adhering to these rigorous experimental protocols, manufacturers and testing laboratories can verify that protective relaying systems maintain functionality without malfunctioning under defined stress conditions. This approach is essential for validating the robustness of electrical infrastructure components against fast transient disturbances. The scope covers specific configurations and response criteria necessary to determine compliance with established technical requirements for electromagnetic immunity in the power industry.
