It is shown that corona discharge leads not only to irreversible losses of electrical energy, but also interferes with the transmission of high-frequency signals, deteriorates insulating elements, can become a source of conditions for the occurrence of a destructive arc discharge and is one of the factors of changing the continuity of the electrical system as a whole. The book describes the processes in a corona discharge that lead to the occurrence of acoustic waves. The authors analyzed acoustic radiation from a corona discharge reproduced in laboratory conditions. The received acoustic signals were processed by Fourier transform. Thus, the features of the spectral function, which belong specifically to the corona discharge in electrical networks with industrial frequency current, were determined. Based on the inverse Fourier transform, asimplified model of the acoustic radiation of the corona discharge was constructed. The authors proposed a method for detecting the presence of a corona discharge based on the spectral characteristics of acoustic radiation. Techniques were developed to determine the presence of a corona discharge for the creation of stationary and mobile devices. The advantages of the method of detecting the presence of corona discharge by the acoustic spectrum are shown. The method makes it possible to determine the presence of a corona discharge remotely, even out of direct sight, regardless of the time of day and regardless of the season. The book states that determining the presence of a corona discharge is not enough, it is still necessary to determine its location. The method of finding the coordinates of the corona discharge as a source of sound was described. Methods of searching for corona discharge coordinates with a fixed scanning device and a moving scanning device are proposed. A UAV is proposed as a mobile platform for the scanning system. The influence of the Doppler effect on acoustic measurements when the UAV speed changes was taken into account. The authors have shown that the use of coronal discharge detection with UAVs will not only enable the prevention of coronal discharge, but also increase the frequency of surface inspections. This will allow timely measures to be taken to improve the reliability of the power system operation. The book is intended for the researchers, postgraduate students and students specialized in theory and calculations of electrical systems. 0aEngineering mathematics.964145 0aEngineeringxData processing. 0aElectrical engineering.965586 0aElectronics.96589914aMathematical and Computational Engineering Applications.24aElectrical and Electronic Engineering.96558824aElectronics and Microelectronics, Instrumentation.9659021 aSokol, Yevgen.eeditor.4edt4http://id.loc.gov/vocabulary/relators/edt9665261 aBabak, Vitalii.eeditor.4edt4http://id.loc.gov/vocabulary/relators/edt9665271 aZaporozhets, Artur.eeditor.0(orcid)0000-0002-0704-41161https://orcid.org/0000-0002-0704-41164edt4http://id.loc.gov/vocabulary/relators/edt9655911 aGryb, Oleg.eeditor.4edt4http://id.loc.gov/vocabulary/relators/edt9665281 aKarpaliuk, Ihor.eeditor.4edt4http://id.loc.gov/vocabulary/relators/edt9665292 aSpringerLink (Online service)0 tSpringer Nature eBook08iPrinted edition:z978303144024308iPrinted edition:z978303144026708iPrinted edition:z9783031440274 0aStudies in Systems, Decision and Control,x2198-4190 ;v50940uhttps://doi.org/10.1007/978-3-031-44025-0 aZDB-2-ENG aZDB-2-SXE c56395d56395
