Locating pipes and cables
Passive Frequencies
Passive frequency detection takes advantage of signals that may already be present on
buried metallic conductors. The supports three types of passive frequencies:
Power, Radio and CPS (Cathodic Protection Signal). You may detect these frequencies
without the aid of the transmitter.
Active Frequencies
Active frequencies are applied directly to the pipe or cable using the transmitter and
are the preferred method of applying a signal to a conductor using the transmitter. The
transmitter can apply a signal using two methods: induction and direct connection.
Induction
The transmitter is placed on the ground over or near the survey area. You select the
appropriate frequency. The transmitter will then induce the signal to any nearby metallic
conductors. In induction mode, using higher frequencies is generally recommended as
they are induced more easily onto conductors.
Direct connection
In direct connection, you connect the transmitter output directly to the pipe or to the
conductor of the cable you wish to survey. The transmitter will then apply an active
frequency signal to the line, which you can locate using the locator. This method
provides the best signal on an individual line and enables the use of lower frequencies,
which can be traced for longer distances.
Connecting the transmitter to a pipe or line requires the use of a direct connection lead
connected to the accessory socket of the transmitter. The red lead is connected to the
pipe or cable and the black lead connected to an earth stake to complete the electrical
circuit.
WARNING! Direct connection to live wires is POTENTIALLY LETHAL.
Direct connections should be attempted by fully qualified personnel only!
