Toning
The Function of Toning
Toning is a method of using a generated signal, or ‘tone’, that is transmitted over a conductor so that
the portion of the conductor buried below the earth’s surface can be located without digging.
The tone is produced at a very low frequency with a transmitter tuned to a particular frequency. The
frequency range available on the transmitter varies between manufacturers but often ranges from
400Hz to about 80KHz. Transmission power is often variable and is usually controlled in a range of
0.033 watts up to 5.0 watts. A ‘radio’ receiver tuned to the transmit frequency is then used to precisely
locate the energized wire.
The set-up requires that a transmitter be attached to the conductive material that will act as an
‘antenna’ and that a ground plane be established at the end of the antenna to close the circuit.
Why Locate ?
- Buried cable assets need to be found by the network owner,
not by a backhoe operator
- Prevent service disruption & repair costs conduit wall
Benefit:
- Eliminates hidden costs
