Abstract

The authors discuss corona and breakdown in compressed sulfur hexafluoride (SF₆) gas-insulated transmission line (GITL) equipment due to free conducting particles. For particle-contaminated conditions, dynamic models of particle movement and particle-initiated corona and breakdown have been developed. Moreover, a method is proposed to utilize externally measured quantities (for example, time to first corona, corona magnitude, and repetition frequency) during testing and commissioning for identifying the size of contaminating particles
