Data testing and processing of electromagnetic radiation produced by 500KV ultrahigh voltage power transmission lines

Abstract

Ultrahigh voltage lines are playing an important role for today's power transmission. The electromagnetic pollution produced by these ultrahigh voltage lines is one of the main environmental problems. Taking the 500kv transmission and transformation in Shangcai-Henan as an example, the electromagnetic radiation of 500KV power transmission lines has been tested in this work. An algorithm of using curve-fitting is also proposed for improving the data precision. Simulation results have shown the effectiveness of the proposed algorithm.
