Abstract :
A magnetic field parallel to the arcing current can improve the breaking capacity of vacuum circuit breakers. In this paper, magnetic field distribution in the radial direction were measured and compared with analysis. A series of short circuit tests were carried out with various condition of contact material and electrode structure. These results were compared with analysis and measurement of magnetic field distribution
