5.5 Routing a cable line – Power mode "Pr"
Routing a cable line is possible with "Pr" power mode. The transmitter should be connected to the
cable line in a manner allowing current to flow through the tested object - Fig. 28. In order to increase
the range of tested line, minimize the mutual cancelling of vectors of magnetic fields generated
around the input and output currents of the transmitter. The impact of the resulting magnetic fields
may be minimized by introducing the transmitter signal to the two ends of the routed line. This method
requires the use of additional extension cord connected to the second end of the line - Fig. 29. Con-
nection shown in Fig. 29 increases the locating range and accuracy. Additional cable must be laid at a
distance exceeding 5-times the expected depth of the cable. The location capabilities of the set are
confirmed for the line with a length of 500m, installed in a depth of 2 meters. For routing the cable
lines and determine e.g. the depth of installing the cables, use dedicated for this purpose locators
manufactured by Sonel S.A.
