Way Of Increasing The Effective Radius Of Detection Of Live Circuits - Chauvin Arnoux LOCAT-N C.A 6681 Manual De Instrucciones

3.4 WAY OF INCREASING THE EFFECTIVE RADIUS OF DETECTION
OF LIVE CIRCUITS
The magnetic field produced by the signal from the transmitter is strongly
conditioned by the shape and size (area) of the loop formed by the "forward"
conductor (connected to the "+" of the transmitter) and the "return" conductor
(connected to the "earth" terminal of the transmitter).
In consequence, in a configuration where the transmitter is connected to the
phase and neutral conductors, constituted by two parallel wires (as shown in
Fig. 23), the effective radius (distance) of detection is not more than 0.5m.
In order to eliminate this effect, connect as shown in Fig. 24, where the loopback
line uses a separate cable to increase the effective radius of detection.
With a cable extender (see Fig. 24), it is possible to obtain a detection distance of
up to 2.5m.
