CABLECOP 300 CABLE DETECTOR

CABLECOP 300 CABLE DETECTION SYSTEM

Current-free and voltage-free, as well as current and voltage conducting cables, can be located with the CableCop 300 cable detector system in electrical circuits of up to 300 V. Cables, conductors, electrical circuits, short-circuits and ground faults can be localized, and protective conduit and coaxial cable can be traced. 
The electrical circuit need not be interrupted, and sensitive electronic components need not be switched off. 
Detection is possible in walls and concrete, as well as underground.



Cable detector system

The cable detection system CableCop 300 
permits both electrically dead and live lines in 
circuits up to 300 V to be reliably detected. 
An interruption of the power supply, or a 
disconnection of equipment containing sensitive 
electronic parts, is not required. 
In particular, the following applications are possible:

  • Location of lines in ceilings, walls and floors

  • Location of line interruptions, switches and fuses

  • Location of short circuits

  • Location of earth faults in three-phase systems

  • Detection of bottlenecks in conduits

  • Tracing of underground cables that are buried in the ground up to a depth of 3 m

  • Tracing of conduits, water and heating pipe lines
    Sorting of installed lines

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 generator S330 for live lines
The signal generator S330 sends high-frequency electromagnetic signals which the receiver R300 can locate along the line to be tested. For this purpose, the signal generator must be connected to this line as well as to a return line. 
The signal generator is designed for lines having AC or DC voltages from 9 to 300 V.
The signal power of this unit can be switched to a lower power so that circuits protected by residual-current circuit breakers can also be connected.

2.3 Transmitter T320 for electrically dead circuits
The transmitter T320 sends high-frequency electromagnetic signals the electric or magnetic component of which can be detected along the line to be tested by the receiver R300. For this purpose, one socket of the transmitter must be connected to this line. The second socket must be connected to ground. 
The unit requires a 9-V battery for the power supply. 
An additional, external power source, e.g. a 24-V NiCd storage battery, leads to a increase in performance.
Storage batteries in the battery compartment are not charged via the external power source.

3 Measurements on live lines with the signal generator S330

3.1 Closed-circuit mode
In this operating mode, live lines are tested with a potential having a maximum of 300 V to
ground.
The load current normally flows in the phase in opposite direction to the neutral conductor,
see connection A. This way, the also opposite magnetic fields are weakened, causing a loss
in signal strength in the receiver. The depth of detection is reduced. 
The same applies when the current flows back across the protective conductor, see connection B.

3.2 General procedure for live lines
Signal generator. 
If the measuring circuit has no residual-current circuit breaker, select the highest signal
amplification.
