Molten Losses on Cut End of Rod Electrodes in AC High Current Arc Discharge

Abstract

When a high current arc discharge occurs in transmission or distribution lines, equipments in those lines are usually damaged by the arc. So, in order to grasp the damage of the equipment, the molten losses of the electrodes made of iron, copper and aluminum have been experimentally stadied in the indoor space with no wind in conditions of arc current from 1 to 60kA, arc duration fromb 0.06 to 0.4 seconds and large electrode separation with no affection by each other. Those are nearly proportional to the integrated values of arc current by time.
