Audible Noise Levels of Transmission Overhead Lines Standard Configurations EHV (Extra High Voltage) Operated in the Czech Republic
Original language description
The environment is deteriorated by low frequency electrical and magnetic field from overhead lines but also by the lines audible noise. Its levels must be controlled by calculations already in the project stage but mainly after new power constructions establishment. The deciding influence on the audible noise level in the EHV overhead lines surrounding is given primarily by surface electrical gradient level of active construction parts in coordination with secondary factors as weather conditions and powerlines active parts pollution. The paper shows calculated and analysed audible noise levels generated by overhead lines of different configurations utilized in the Czech Republic. The surface electrical gradient influencing the line audible noise of conductor wires can be controlled by operational voltage and many different construction parameters. The analyses result in important knowledge for configuration design, operation and also for the overhead line trace choice.
