5.2.3 Increase of the effective radius when tracking the loaded current circuits
When the transmitter is connected directly to the phase cable and the neutral cable, the signals are led to
two parallel current circuits. Therefore, the twisting of circuits can sometimes cause signals that
counteract each other, which brings to the result that an effective search radius is at most 0.5 m. To
eliminate this effect, the connection must be made as in the following figures, where the loop cable uses a
separate cable to increase the effective radius to about 2.5 m. Loop cables for longer distances can be
prepared with the help of a cable roll.
Follow and observe the safety instructions when connecting loaded current circuits to the transmitter.
Pay attention to the distance between the transmitter and the searched current circuit in order to be able
to determine the current circuit over the signals clearly.
-
The stronger the signals displayed on the display of the locator during the tracking of the current
circuit, are, the closer the searched cable is to the locator.
-
Set the power of the transmitter in order to adjust it to different search radii.
-
Select the manual mode on the receiver and the appropriate receiver sensitivity in order to locate
the current circuit accurately.
