Abstract

High altitude areas often lead to more serious corona discharge, and produce more serious electromagnetic environment problems such as audible noise and radio interference, which greatly restrict the selection of transmission lines and cause certain environmental problems. In order to study the characteristics of audible noise in high altitude areas, Yangbajing Town, Lhasa, Tibet Autonomous Region, China (altitude :4320m) and Wuhan city, Hubei, China(altitude :20m). The audible noise characteristics of three different lengths of discharge fine copper wires in high altitude areas (0.8mm, 1.0mm, 1.2mm) were tested. The influence of applied voltage and wire diameter on corona audible noise in plain area and high altitude area is analyzed. The research can provide important data reference for the study of electromagnetic environment in high altitude areas
