Method for partial discharge source location, especially in the oil energy transformer based on description maps of acoustic emission in the frequency domain

摘要

way location sources discharge niezupeu0142nych especially in transformer insulation oil energy based on acoustic emission maps descriptors within the band of frequencies is,in the first stage, a set of descriptors calculated for adc frequency 110 - 200 khz for acoustic emission signals recorded at the measuring points of the planar side of transformer tank, in the second stage, a map of des kryptoru00f3w krigingu method, and in the third stage.by using of the isolines of descriptors specify local maxima, which lokalizuju0105 source discharge niezupeu0142nych zrzutowane the vats test transformer.
