Detection of Corona Discharge in Power Supply System
摘要
Chapter deals with the issues related to the detection of corona discharge on the elements of the power supply system. The methods of corona discharge detection by different types of medium stirring are investigated: by ultraviolet radiation, by infra black sea radiation, by the present electromagnetic background, by the presence of a chemical compound, and by detection of corona discharge by the method of fixation acoustic radiation. The description of the processes in the corona discharge, which are the sources of acoustic radiation, is given as the origin of the ionic current and the stream of displacement in the outer corona discharge zone. The experiments on the acoustic radiation of the corona discharge were carried out. The results of acoustic measurements are presented. The results of acoustic signals processing of the corona discharge are presented.
