3.3 TWO-POLE APPLICATIONS

3.3.1

CLOSED-CIRCUIT APPLICATIONS

These can be applied to both live and dead circuits:
In dead circuits, the transmitter merely sends coded signals to the circuits to be
detected.
In live circuits, the transmitter not only sends coded signals to the circuits to be
detected, but also measures the voltage present, as shown in figure 18:
Remarks:
This method is ideal for locating outlets, switches, fuses, etc., in electrical
•
installations that have sub-distribution electrical cabinets.
The depth of detection varies according to the medium in which the cable is
•
located and according to the manner of use. It is generally less than 0.5m.
Adjust the power transmitted by the transmitter according to the various radii
•
of detection.
