TYHD-A3/110 OverheadLine Communicable Fault Indicator is applied to 110kV overhead line ,is a device to indicate line fault current. This system is composed of two parts, one is gathering unit and the other is collection unit.gathering unit monitors line running status real-time. When fault happened ,the gathering unit can quickly locate phase-phase short-circuit area,the fault line and fault point can be judged quickly and accurately.in the meantime, the alarm flag turn red and appear flashlight and the fault signal also be transmitted to collection unit. After receiving signal from gathering unit, the collection unit send the received data to master monitoring station through wireless communication (GPRS/CDMA etc.)

The master station monitoring software analyze the received data and network topology, then to confirm the fault location and appear audible and visual alarm signal, in the meantime, the master station send the analyzed fault information to the operator’s cellphone and help them to find the fault point quickly, it reduces the power-off duration and improve the power supply reliability.

Insatallation :

a) By fitting the bracket installed in the hot sticks, screw detaching sheet nut to let the sheet fully retracted into the interior of the column (ie: try to tighten the sides, leaving enough space so as not to block the indicator when installing).

b) put the indicator into the bracket , and make the spring device to hook with the indicator spring, and rotate the spring device down firmly until after the indicator spring pulled position retractor can hook, then hook the spring with retractor and pull t he spring device out. And use the same method to the other side of the same end of the indicator spring to hook retractors.

c) Aligning the overhead lines pushed up and under the pressure of the overhead lines the indicator springs are divorced from the retractor spring and stucked overhead lines firmly.
