3. Cable route tracer(Cable fault comprehensive tester) (XHGX507)
Description
XHGX507 underground cable pipe locator is mainly used for cable fault location, cable identification, cable path and depth measurement. It can complete tasks that could only be accomplished by a few sets of instruments in the past.
Working principle
The underground cable pipe locator is designed based on the electromagnetic induction method and the application of the communication principle.
1.The electromagnetic signal is generated by the transmitter, and the signal is transmitted to the underground cable under test through different transmission connection methods.
2.After the underground cable induces the electromagnetic signal, an induced current is generated on the cable, and the induced current propagates along the cable to the distance.
3.In the process of current propagation, electromagnetic waves are radiated to the ground through the underground cable. When the receiver detects on the ground, the electromagnetic wave signal will be received on the ground above the cable.
4. The position, direction and fault of the underground cable can
be judged by the change of the received signal strength.
Features
The large-screen LCD displays the signal strength, and the bar, arrows and voice prompts make it easy for the operator to judge the underground position of the cable and the fault point. One person can do it all.
