TYHD-AI3 smart grounded and short circuit fault passage indicator is installed on the overhead power lines, is to detect the grounded and short circuit fault for overhead line. It will alarm during the day and flash during night to show the fault.According to the alarm information , the operator can locate the fault area quickly and find out the point of fault, which supply the best solution for the difficulty in finding fault area. This device can improve work efficiency, reduce power outage time and power restoration quickly.
When short-circuit happen in line, the fault current passage is from fault point to substation,all indicators which the fault current flows through will sense the current sudden changes.with the switch tripped at exit of substation, the line will be in status of loss of voltage and current. Short-circuit adopts method of load current self-adaption intelligent sudden changing way.
