Generation of critical acoustic pulses in high-voltage insulators due to induced fields of partial discharges by V. A. Golenishchev-Kutuzov, A. V. Golenishchev-Kutuzov, A. V. Semenikov, G. D. Mardanov, R. I. Kalimullin, D. A. Ivanov

Subjects: “…the purpose of the article is to discuss an updated survey of the technical condition of porcelain high-voltage insulators of the type ios 110/400, which had defects with partial discharge intensities above 4 nc, at tatenergo substations. the experiments were carried out with simultaneous use of electromagnetic and acoustic research methods. during the analysis of the results obtained, the influence of the fields of previous powerful partial discharges on the technical condition of high-voltage insulators was established. the physical features of detecting powerful partial discharges by electromagnetic and acoustic methods have been studied. the conducted studies allow us to draw the following. conclusions: the previous partial discharges can create additional long-lived electric fields on the dielectric surfaces of defects that exceed the field of the applied operating voltage in intensity…”
