Měření částečných výbojů na zařízení VN a VVN

Abstract

The aim of this thesis is to process information related to partial discharges. Their characteristics, species and types. Describe what are their symptoms, effects and interaction with the surroundings. One important part of this work is part of the interference, because nowadays using a large number of electronics is a significant part of the partial discharges. This paper describes the principles and methods of measurement of partial discharges. It also shows how the measurements are performed on equipment distribution group CEZ, which is used measuring techniques and procedures used to evaluate the defects found. To approach the issue of partial discharges there are some defects in the operating device. At these defects are illustrated by measuring instruments and the comparison between some of them. On the photographs are included to measure background.
