Spectral-correlation method of investigation of highvoltage electrical insulation components

Abstract

The description of the experimental method and setup for investigation of homogeneity of high-voltage electrical insulation components by spectral correlation method is given. The basic principle of the spectral-correlation method and method of processing of the received images are discussed. The results of studies of electrical insulation paper made of coniferous wood, in particular pine, as well as bamboo, bacterial cellulose, contaminated dielectric fluids and cross-linked polyethylene (XPLE) are presented. The opportunity of using spectral correlation method to determine the parameters of high-voltage insulation for electrical and electronic engineering is shown.
