Abstract

The author considers a method for evaluating the condition of high-voltage insulation equipment based on measurements of a few characteristic parameters. Results of preliminary tests of models of the insulation are the basis of the evaluation of the service life of actual equipment. The method is based on the mathematical correlation between electrophysical characteristics measured on the actual equipment and similar characteristics measured on samples of insulation. A methodology is developed for determining the correlation between electrophysical characteristics of the insulation and both temperature and electric intensity and also the influence time of these factors (either combined or separate)
