“…Subsequent investigations (e.g. (Pocomy Schlomann, Bames,: Miller, 1972) took note of the "pure tone" emission at twice mains frequency and recorded some values in dependence upon configuration (Pocorny Schlomann, Barnes, Miller, 1972) but based their further evaluation on A-weighted AN. It was concluded, (Pocorny Schlomann, Bames, Miller, 1972) that there is no unambiguous relationship between such A-weighted AN and bundle configuration (number and diameter of conductors) at a given surface gradient.…”

The origin of the Iocally unacceptable and intensive tonal 2f = 100 Hz emission from overhead high voltage lines has been clearly traced by means of multiple diagnostics applied to a model line in the laboratory, Use of a special hydrophilic surface preparation has demonstrated a significant reduction of tonal acoustic noise emission after heavy rain. Ursprung und Verminderung tonaler L#Jrmemission von Hochspannungsleitungen.Der Ursprung ron an manchen Orten unannehmbar ernpfundenen tonalen 2f= 100 Hz Larmemissionen von Hochspannungsleitungen wurde durch Anwendung vielfacher Diagnostikmethoden auf eine Modellanordnung im Labor eindeutig gekl~rt. Bei Anwendung einer speziellen hydrophilen Oberfl~chenbehandlung wurde eine betr~chtliche Reduktion der akustischen Gesamtemission nach schwerem Regen nachgewiesen.

“…The air near the wires will be repeatedly ionized under the action of the electric field to generate sound, light, and heat [9][10][11]. The above phenomenon not only results in noise pollution into the living environment of the nearby residents, causing misgivings about personal safety, but also leads to power loss [12][13][14][15][16]. Therefore, it is important to suppress the corona discharge of high-voltage transmission lines.…”

In recent years, the number of high-voltage transmission lines has sharply increased with the rapid development of modern industry. However, a corona discharge phenomenon often occurs on the exposed high-voltage transmission lines, leading to energy loss and noise pollution. Herein, we have proposed a facile spraying method to prepare a superhydrophobic and thermally conductive coating to restrain the corona discharge phenomenon of high-voltage transmission lines, with vinyl silicone oil and hydrogen silicone oil as the main materials and modified boron nitride (BN) as a thermal conductive filler. The obtained composite coating exhibited superhydrophobicity, with a high water contact angle of 162°. In addition, the coating also showed a good self-cleaning capability, non-adhesion capability, mechanical stability, and chemical stability. Owing to the construction of the thermally conductive pathways with BN, the thermal conductivity of the coating reached 1.05 W/m·K, which was beneficial to quickly dissipating the heat generated by the current heating effect. Moreover, the corona losses of the positive and negative electrodes under simulated rainy conditions were decreased by 7.43% and 8.05%, respectively. The findings of our work have provided a new strategy to effectively restrain the corona discharge phenomenon of transmission lines, showing great application potential in the field of high-voltage power networks.
