Underground Fiber Optic Fault Locator For Displaying Fault Signals By LED Flashing Lights

optical fiber communicable for underground cable display the fault signals using LED flashing lights


TYHD-1 panel type fault indicator(be called indicator for short below) is mainly used for indicate short circuit fault and earth fault on the On/Off panel, and used for output wireless signal.

The principle is micro-controllers with little power consumption, micro-controllers can automatically identify fault signals from short circuit indicator and earth indicator, They can display the fault signals using LED flashing lights on the spot and output the signals by wireless.

The appearance of the indicator :

Specification of installing:

L1 is connect with A live line

L2 is connect with B live line

L3 is connect with C live line

L4 is connect with Earth line

V1.08 is the version number of software

Fault indicate function:

The lights on the L1,L2,L3,and Earth buttons will flash with a 5-minutes interval,if the short circuit fault or earth fault occur.This can be returned to the original condition automatically according to the time delay set by the factory or by pressing button of “Reset/Test” manually.the low battery capacity of the indicator is show on the panel by wireless,The indicator of low battery voltage will flash at the same time(with 4 seconds interval).
