How To Find And Trace A Buried Live Or Dead Cable Or Metal Pipeline
The locator is composed of two main parts, transmitter and receiver.
The transmitter's job is to generate a signal with a modulated intensity.
This signal by turn generates a magnetic field around the target conductor.
So the magnetic field is sensed by the receiver coil to induce a voltage within it.
In live current cables there is no need for the transmitter, as the receiver will detect the magnetic field already generated around the cables which have a current flowing in it.
In dead power cables which have more than one phase cable, the user should connect one phase at a time to the transmitter probe (Red), and the other phases should be connected to the other probe (Black) and to the earth line.
In the second case, the transmitter will send a signal to flow through the phase cable, in order to generate a magnetic field around the conductor, where the receiver will detect it in his turn.

Operation steps:
Open circuit applications: tracing cables, metal pipes inside wall, metal pipes inside floor
- First, be sure that the circuit is dead (no voltage is applied).
- Connect the transmitter black probe to an effective earth line.
- Connect the transmitter red cable to the phase required to be traced.
- Press the power button in the transmitter.
- Press the power button in the receiver.
- Move the receiver along the wall to trace the cable.
- Notice the received signal intensity on the led display of the receiver, and also using the sound indicator.
- Tracing the heating metal pipes are similar to the one pole cable tracing case.
Complete circuit application: detecting short circuit; wire sorting; detecting sockets; detecting switches
- Both for live or dead current circuits.
- The two transmitter probe will be connected to a wall socket.
- Dead circuits will be supplied by the transmitter battery.
- In Live circuits the circuit will supply the transmitter automatically, saving the battery power.
- Power on both transmitter and receiver.
- Use the receiver to trace the cable lines required.
