Abstract
The features of the developed complex remote method for diagnosing the current operating condition and predicting the residual life of high-voltage insulators under operating conditions are considered. The basis is the registration and subsequent computer analysis of a set of experimentally established diagnostic parameters of partial discharges. To find and localize the location, type and degree of danger of defects, a two-channel contactless method of registering partial discharges using electromagnetic and acoustic sensors as part of narrow-focused antennas is used. Special attention is paid in the article to the influence of the most dangerous defects arising due to induced electric fields created by previous partial discharges.
