A magnetic-type air circuit breaker for 15,000-volt services

H. V. Nye (Allis-Chalmers Manufacturing Company, Milwaukee, Wis.): This paper is an interesting description of the difficulties encountered in trying to develop the air magnetic type of circuit breaker into a reliable interrupter for 15,000-volt service. The first thing that impresses the reader after looking over the data and sketches submitted with the paper is the complexity of control and arc runner structure attained by the introduction of six separate magnetic-blowout systems into one arc chute.
