Description
Summary:Results of physical simulation of the impact of discharge phenomena generated by an artificial thunderstorm cell, which involve structural elements made of dielectric and composite materials, on the elements of control and monitoring systems of power facilities are presented. An increase in the curvature radius of the tip of the model initiating electrode, which is in contact with the surface of the insulating structure, is shown to result in an increase in the amplitude and steepness of the current pulse of the streamer corona and the amplitude of the signal induced in a flat antenna, on average, by a factor ranging from 1.5 to 2, and a decrease in the neutralized charge of the cloud. It has been found that, at the streamer and main stages of the discharge, the amplitude of the current and the flown charge diminish with an increase in the curvature radius of the model electrode tip. The dependences between the maximum value of the signal induced on the antenna and the amplitude of the current at various discharge stages are determined. As the steepness of the current pulse at the streamer and main stages of the discharge between a model electrode with a large curvature radius and an artificial thunderstorm cell increases, with the amplitude of the signal induced in the antenna also increasing.
