Abstract
Results of the spectral analysis of electromagnetic signals induced in a model antenna by discharges from an artificial thunderstorm cell involving structural elements made of dielectric and composite materials are presented. The spectral analysis has been performed using the “Mexican Hat” basic wavelet. The influence of the curvature radius of the tip of the initiating model electrode contacting the surface of the dielectric structure on the spectral composition of the induced signals is investigated. The spectral composition of the discharge current during the formation of a streamer corona with a larger radius of tip curvature exhibited characteristic frequencies with higher values that are several times higher. The spectrum of the signal induced on the antenna contains characteristic frequencies that are higher than those in the discharge-current spectrum. The characteristic frequencies of the signal detected by the antenna during the formation in the electric field of a streamer corona and the upward leader from the initiating electrode with a small radius of curvature in contact with the insulator surface were 20% higher than those in the case when the discharge developed from an electrode with a large radius of curvature. During the formation of the main stage of the discharge, the average values of the maximum frequencies of the signal induced in the antenna had similar values. The frequency that corresponds to the maximum intensity of the signal wavelet spectrum tends to decrease with an increase in the steepness of the streamer corona current pulse. In analyzing the possible effects of atmospheric electricity and lightning on elements of monitoring and control systems of power facilities, it is necessary to take into account that the electromagnetic radiation spectrum of discharges developing from structural elements near the surface of composite/dielectric materials includes frequencies up to 70–80 MHz.
