Localization of Insulation Defects in High-Voltage Equipment Using the Visual-Acoustic Method

The article discusses the importance of assessing the technical condition of electric grid equipment in modern conditions, given the high level of equipment wear. The authors emphasize that this assessment is a mandatory and integral part of ensuring the reliable operation of electrical networks. The paper presents a case study where the authors use visual and acoustic inspection methods to examine high-voltage substation equipment at various voltage levels. Based on these findings, they propose criteria for assessing discharge activity and use it to determine the technical status of insulation. The authors suggest that these criteria can be applied to a wide range of electrical systems, helping to prevent equipment failures and ensure the safety of power outages.
