Hydro-Quebec's concerns regarding circuit-breaker reliability are presented. The first section focuses on two aspects crucial in determining line-charging-current breaking capacity: the arc duration and the test circuit configuration. The second part discusses the importance of manufacturing quality for the arcing contacts, nozzles and gaskets. The third part, which is based on test results obtained for different breakers, gives the test criteria at 20 C for simulating breaking tests a [minus] 50 C. Hydro-Quebec's requirements for testing the tightness of SF[sub 6] breakers are set forth in the last section, together with a reliable leakage-measuring method.
