Used to judge the short circuit fault indicator diagram

short circuit judgment

As line 2# B phase 2,5,8 indicator and line 2# C phase 3,6,9 indicator turn red, but the 11,12 indicator still show white, that judged the point D happen short circuit.

Used to judge the earth fault indicator diagram

Earth fault judgment

As line 2# C phase 3,6,9 indicator turn red,but the 12 indicator still show white, that judged the point D happen earth fault.

Fault Indicator Installing and Uninstalling

Fault indicator installing guide


1.Put the indicator into the installing cup and let the spring up by U-type spring lifter. (Installing cup fixed with hot stick.)


2.Fix the spring by hook in the installing cup. Make sure two spring all fixed by hook of two side.pull out the U-type spring lifter.

4.Pull down the hot stick with installing cup, the indicator would be fixed on the cable. If failed repeat from 1 step. (Be careful of falling off)

 Fault indicator uninstalling guide


1.Fixed the installing cup on the hot stick, Relax the iron sheet on the both side of the installing cup. Make the iron sheet like two hooks.


2.Aim to the uninstalling indicator, then upward force, until the iron sheet lock the indicator.


3.Pull down the hot stick slowly until the indicator is separated from the cable.


4.Push the iron sheet on the both side of the installing cup. Make the iron sheet retract, take out the fault indicator.
