It disrupts AM radio broadcasting, analog television signals, and emergency communication networks.
. It specifies the laboratory procedure for measuring the radio interference (RI) characteristics of insulators used on AC or DC overhead power lines and traction lines with a nominal voltage greater than 1,000 V. iTeh Standards The latest version is Edition 3.0 , published in December 2023 iTeh Standards Key Technical Specifications Test Environment: Tests are performed in a laboratory on clean and dry insulators. Measurement Frequencies: Standard frequencies: 0.5 MHz or 1.0 MHz. Reference frequency: Alternative range:
Here's a brief write-up:
The standard specifically addresses tests performed on in a controlled laboratory environment. While factors like moisture, rainfall, and pollution significantly affect radio interference in real-world service, IEC 60437 focuses on dry conditions to ensure results are reproducible across different testing facilities. Its primary goal is to ensure insulators comply with electromagnetic compatibility (EMC) requirements and do not disrupt communication systems. Technical Requirements
, the maximum permissible radio interference voltage (RIV) for a 400 kV transmission line is often set at 1,000 microvolts at 1 MHz
Atmospheric conditions significantly alter corona inception voltages. IEC 60437 requires meticulous recording of: Ambient temperature Air pressure Relative humidity
A: No, but you must check the IEC website for "corrigenda" (error corrections). The 2019 CSV version is current as of this writing.
