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.

Description

JW FISHER CT-1 CABLE TRACKER

The ideal tool for tracking power and communication cables

JW Fishers CT-1 cable tracker 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 breakpoints that are exposed to water.

The JW Fisher CT-1 cable tracker 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 JW Fisher 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 inducted 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 fewer 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.

 

  • Custom Frequencies: A custom Cable Tracker is available that will transmit and receive frequencies other than the standard 25Hz, 50Hz, 60Hz, or 1024Hz. Contact factory for pricing.
  • Carrying case for Probe and Signal Injector: $375
  • Dual Underwater Headset: $195

FISHER CT-1 CABLE TRACKER

JW Fishers CT-1 Cable Tracker 1 is a precision electronics system with a commercial-grade Signal Injector and Cable Tracker Probe. Specially designed to locate and track buried cables including power and communications cables, the system locates cables buried on land or underwater. The CT-1 will also identify the fault or breakpoints that are exposed to water.

Fishers Signal Injector: The Signal Injector control box is used to create a constant current electromagnetic field around the cable at 25, 50, 60, or 1,024Hz. The Signal Injector is connected to the shore end of the cable and the Cable Tracker Probe tracks the electromagnetic signal along the length of the cable.

In most cases, the 1,024 Hz signal is injected because the higher frequency makes less interference from surrounding power wires. The 25 Hz signal is often used by the military for tracking cables. The Signal Injector has a switch to select 25, 50, 60, or 1,024 Hz, and a control knob to adjust output power. A low current setting (100 mA) is used for most cables and a higher power (up to 500 mA) is used for hard-to-find cables. Once the output power level is set, the output current is automatically regulated to give steady Probe readings. The Signal Injector is powered by 120 volts AC, or 220 volts AC with an optional transformer.

Fishers Probe: The Cable Tracker Probe operates on its own internal 9-volt battery pack. The Probe frequency switch can be set at 25, 50, 60, or 1,024Hz to match the signal source. If the cable to be located in a 50/60 Hz power cable, it can be tracked underwater without the use of the shore-based Signal Injector. However, when tracking power cables on land the 1,024 Hz frequency may have to be used due to 50/60 Hz noise in the air. If the cable to be located in a live multi-conductor communications cable (no AC power lines), the 1,024 Hz frequency is used and will pick up the cable without using the signal injector.

As the probe approaches the buried cable, the signal gets stronger in the earphone and more segments are lighting up on the LED bar graph indicating a stronger signal. When the diver is directly over the cable the signal will suddenly drop to near zero (called the null-spot). If the diver goes past the cable, the signal will jump to full scale again. The cable is easily pinpointed by pointing the Probe directly at the bottom and slowly moving the probe back and forth. The probe will be pointing directly at the cable when the readout goes null.

Depth of burial can be calculated by taking a second reading with the probe held at a 45-degree angle and a second null point obtained. The depth of burial will be the same as the distance between the two null points on the surface.

So effective is the Cable Tracker 1 system for tracking and pinpointing cables, that in many cases the cable can be located and tracked from a small boat on the surface. The operator holds the nose of the Probe in the water and operates it as stated above for the diver. Once the cable is located and tracked from the surface, the diver enters the water and descends to the bottom where the cable is pinpointed.
