The paper presents experimental research into the corona noise performed on a 400 kV overhead power line with a horizontal disposition of conductors. The high-voltage power line in its role of a communication channel is a source of different noises, characterizing an important feature of this communication media. The main objective was measuring and modeling the corona noise. Measurements of the power spectrum density and relative corona noise within a power frequency period are presented for different weather conditions. The algorithm for measuring variations in the corona noise level is described on the basis of noise samples. The maximum peaks exceed the root-mean square noise level by 7.95 dB in foul weather conditions and by 2.9 dB in fair weather conditions. An appropriate computer model of the corona noise compliant with the measurement results is proposed.
