Abstract

It is very important to know the insulation recovery time after arc interruption for selecting the adequate reclosing dead time of rapid auto-reclosing on transmission lines. In order to study insulation recovery characteristics after arc interruption on UHV (1000 kV class) transmission lines, many tests were carried out. Full size insulator assemblies were used for measurements of insulation recovery characteristics after arc interruption, and the behavior of post arc gases, which strongly influence the insulation recovery characteristics, was investigated. In this paper the authors describe the behavior of post arc gases after arc interruption of UHV transmission lines
