Abstract :
This paper deals with test methods to evaluate the effects of high current fault arcs occurring in electrical switchgear compartments stressing insulating walls made of different materials. These partitions are stressed mechanically and thermally. To study these effects several test arrangements were developed and relevant experimental studies performed. The performance of the investigated materials is presented and discussed
