Fishers CT-1 cable tracking system was specifically designed
to locate and track deeply buried power and communications
cables. The cable tracker will locate cables on land or
underwater. The CT-1 will not only track cables, but also identify faults or
break points that are exposed to water.
The CT-1 system consists of a shore based Signal Injector box
and the Cable Tracker Probe. The Signal Injector is
connected to the shore end of the cable and the Cable Tracker
Probe is used to track the electromagnetic signal along the
length of the cable.
If the cable is a
power cable transmitting at 60Hz (USA) or 50Hz (Europe), it can be tracked without the use of the Signal Injector.
The CT-1 Probe will detect the 50Hz or 60Hz signal in the power
cable. If the cable
is a live multi-conductor communications cable, the signal
injector will not be needed, the probe will pick up the 1024Hz
signal. If it is a dead cable, or a fiber optics cable, the Signal
Injector box must be used. The
box is connected to the surface end of the cable. It
creates a constant current electromagnetic field around the
cable at 25, 50, 60, or 1,024Hz. The operator selects the
frequency to be used.
Once a signal has
been induced into the cable, the Cable Tracker Probe frequency
switch is set to match the frequency; 25, 50, 60, or 1,024Hz.
The Probe receives the signal being transmitted and indicates
the strength through both visual and audio readouts. First the
cable is located and tracked on the surface, then the diver
enters the water. The Probe is submerged and swept back
and forth until a signal is received. When the probe is
pointing in the direction of the cable, a null point is heard in
the earphone, and less LEDs will
illuminate on the display. As the diver descends to the bottom
the signal is easily followed and the precise location of the
cable can be pinpointed.
 The CT-1
cable tracking system is so effective that in many cases the cable can be located and tracked from a
small boat on the surface as the operator holds the nose of the
probe in the water.
Power
is supplied by six internal AA rechargeable batteries that will
power the CT-1 probe for 2-3 hours. The included battery charger
connects to any 120 ac voltage source (a 220 ac charger
transformer is optional). Disposable alkaline batteries
can also be used to power the Probe.
The CT-1 is
constructed of corrosion proof urethane and PVC to give many
years of trouble free performance. The modular construction
allows for easy field repair should it ever be necessary. The
complete system is covered by a TWO YEAR WARRANTY.
