Non-Contact Methods for High-Voltage Insulator Diagnosis

The article is devoted to the developed non-contact methods of NDT for dielectric elements of electrical equipment during operation under operating voltage. The experience of a team of authors in the development of devices and methods for the diagnosis of partial discharges in high-voltage insulators is presented. Based on the developed devices and programs for processing diagnostic information, a system for monitoring the technical state of high-voltage insulation under operating voltage was created.
