The final results of the CIGRE second international inquiry on the reliability of high voltage circuit-breakers in service are presented. In the seventies the first international inquiry, that covered all technology circuit-breakers, was conducted. The second international inquiry was limited to single pressure SF6 gas circuit-breakers, thus showing the improvements due to this technology. The main conclusion is that the reliability concerning Major Failures has increased considerably and that the maintainability of modern SF6 circuit-breakers is much better than the older technology circuit-breakers. Also the conclusions from several other studies, based on the results of the inquiries, are presented.
