The cable fault testerunder UHV power can help many power workers conduct various power tests more conveniently.

a) If the "output" overload signal or the tested cable has a short circuit phenomenon, the "overload" indicator light of the routing instrument will light up, and the signal source will have no output; At this time, the source output adjustment should be reduced or the short circuit of the tested cable should be eliminated

(It is best to use "good phase"), then press the "start" button to make the signal source work normally

b) Before testing, operators should carefully read the operation manual and proficiently operate the instrument; During the detection process, the "adjustment knob" should be kept stable, so that the sound of the headset can be stable and reliable. All of these can ensure that the detected results are accurate. Therefore, the proficiency and accumulated operational experience of operators are one of the necessary prerequisites for successfully detecting cable paths.

c) Always make clear and reliable inspection marks to avoid unnecessary rework and retesting.

d) After turning on the power switch, the light does not turn on. Please check the fuse.

e) Strictly follow the operating procedures of the power industry, operate safely, ensure personal safety and equipment integrity, and ensure smooth testing and inspection.
