Abstract :
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.
