Product Details
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.The installation and
uninstalling way is very simple and convenient.
The parameters can be modified by client's requirement. default
