| Abstract: | This paper presents results on the optimisation of a miniature current limiting circuit breaker, operating in 240 Vots, ac supply. An optical fibre imaging system is used to i. dentify arc root motion, with short circuit current up to 6kA. The optical fibre array uses software image processing to identify the position of the arc roots in the arc chamber. Identification of the arc roots allows a study of arc immobility. Results are presented on variation of the moving contact material and arc runner material on arc root motion for one geometry. |
