The Effect of Temperature and Humidity on Audible Noise Generated from UHV DC Transmission Lines
To research the effect of temperature and humidity on audible noise generated from UHV DC transmission lines, a mini corona cage has been constructed and put in a manual environment room, which temperature and humidity can be controlled. At the same time, an audible noise performance measuring system by using A/C weighted network audible noise meter and 8 kHz acoustic sensor have been set up too. The audible noise generated from a copper line have been measured in a mini corona cage not only at different humidity from 30% to 95% but also at different temperature from 0degC to 30degC. The relationship between audible noise level and temperature and humidity have been observed.
