Utility Line Location
Southern California's Source For Utility Line Location And Property Inspection
Non-Destructive Testing
(888) 679-0953 - 24 Hour Appointment Line
The cable detection system consists of a signal
generator for live lines and a transmitter for electrically dead lines
as well as a receiver.
Signal generator and transmitter feed high-frequency electromagnetic
signals into the line to be tested. Along the line, these signals are
converted into acoustical and optical signals by the receiver.
The signal strength is a measure for the location of the line.
Two basic operating modes are to be distinguished hereby: |
1 ) Closed-circuit mode :
In this mode, live lines are tested with a potential of a maximum of
300 V to ground.
The signal current of the signal generator, for example, is fed into the
phase of the line to be tested and flows back to the signal generator
through neutral conductor across the transformer.
This "two-pole" application corresponds to a closed circuit, whereby the
energy for the generation of the signals is directly derived from the
system. In the case of a shorted line, the current flow in the circuit
to be measured is interrupted, a 9-V battery can, for example, be
connected into the measuring circuit as a substitute power supply.
The receiver evaluates the magnetic component of the signal.
2) Open-circuit mode :
In this operating mode, only electrically dead lines may be
tested.
One output of the transmitter is connected to the line to be tested, the
second output to ground.
This "single-pole" application corresponds to the principle of a radio
transmitter.
The connected line hereby becomes the antenna of the transmitter, the
ground serves as reference potential.
The energy for the generation of the signals is provided by the internal
battery.
The receiver evaluates the electrical component of the signal.
2.1 Receiver R300
The receiver R300 has two built-in detectors which receive the
different signals from the signal generator for live and electrically
dead lines. These signals are indicated both optically and
acoustically:
Optically by a diode assembly with which up to 10 diodes light as a
function of the signal strength.
A red filter permits reading also in the case of direct incidence of
sunlight.
Acoustically by a sound generator.
2.2 Signal |
Cable Detection and Avoidance
Buried Utilities and cables represent a major hazard to any
construction worker. Obtaining accurate information about the
location of the various installed services pipes, cables and
utilities under the ground is a necessity before starting any
excavations. It is the full responsibility of every company or
person to verify the drawings from the utilities and avoid
damaging existing services, pipes and cables.
Survey Systems Ltd supply a wide range of cable detection
products from leading manufacturers such as Leica, C-Scope and
Radiodetection. By clicking on the links above you can view the
full range of cable detection equipment and also buy or hire the
cable detection equipment.
Via receiving reradiated radio frequencies through
internal aerials, detecting the strength and direction of the
received signals, the operator is given the location and
direction of the underground service, pipes and cables. Mark the
location of the service, pipes and cables on the surface of the
ground, giving the excavation team clear indications of where
not to dig.
