Abstract

PURPOSE: To make it easy to decide the direction of any fault point even when under such a condition that there are many faults of armoring insulator (fault points of insulating resistance to ground) and stray currents are flowing in the shield, by forcing a much larger signal current directly into an ampere meter on one side from the fault point.
