Diagnostika vysokonapěťových izolovaných venkovních vedení

Abstract

The aim of this thesis is the diagnosis of isolated high-voltage overhead lines. Surveys what effect the temperature, humidity and various faults of insulation XLPE insulated wires hanging. The theoretical part describes methods for the diagnosis of partial discharges. Describes how their involvement, and ability statements. It also determines the geometric description of the hanging of insulated wire and divides the partial discharge. The practical part describes the preparation work, climatic chamber with a measuring device and a final evaluation of long-term measurement of partial discharges hung insulated wire that is running PAS-W.
