Abstract The article introduces the electromagnetic radiation characteristics of 220 kV and 500 kV high-voltage overhead transmission lines and their impact on weather radar.It elaborates in detail on the electromagnetic radiation testing process and results of high-frequency and microwave frequency bands of transmission lines under different voltage levels.The study concludes that the electromagnetic radiation of transmission lines is closely related to voltage levels,and verifies the correctness of the protection distance specification for high-voltage overhead transmission lines from an application perspective,intended to provide reference and inspiration for the environmental site selection of large electronic equipment and large radar.
