Measure and pinpoint sheath and conductor faults, locate cable path/depth quickly and easily with this lightweight, easy-to-handle unit

 

When used in conjunction with the 3M™ Dynatel™ 2205 EMS Marker Locating Accessory, the system can:

  • Pinpoint the exact location of buried EMS markers
  • Trace a cable path while simultaneously finding buried markers along the way

 

The 3M™ Dynatel™ 2273 Cable/Fault Locator is a microprocessor-based system that incorporates advance digital signal processing techniques to quickly and efficiently locate sheath (earth return) faults and trace the path of underground cables, both copper and fiber optic (with metallic trace wire). Lightweight, compact and wellbalanced, the 2273 cable/fault locator accurately:

  • Locates cable path
  • Measures cable or sonde depth with the push of a button
  • Measures signal current in the cable
  • Pinpoints sheath faults and cable breaks
  • Discriminates between light and heavy faults
  • Identifies cable and cable pairs
  • Tones shorts and grounds in aerial cable
  • Identifies cable pairs through wet sections
  • Locates energized power cable

The 2273 cable/fault locator provides accurate cable or sonde depth measurements, giving a digital readout in inches, feet and inches, or centimeters (user-selectable).

Four modes of operation for accurate locates, even in congested areas

For cable path locating, the Dynatel 2273 receiver uses one of four user-selected locating modes — dual peak, dual null, differential or special peak (which increases the sensitivity of the receiver for tracing over longer distances). The mode is selected depending on which is most effective under the locating conditions.

The receiver includes four volume settings, including a special “expander” function that makes peaks and nulls more pronounced. The expander feature enhances the amplitude difference between two conductors carrying the same signal, making the unit extremely accurate, even in congested areas. A headphone jack is also included.

Precisely locates faults

The 2273 cable/fault locator can precisely locate sheath (earth return) faults on both short and long cable sections. The unit sends a trace signal simultaneously with a faultlocate signal, allowing the operator to use the cable-locate function when locating sheath faults in long cable sections. Sheath (earth return) fault strength is indicated on the receiver LCD display, allowing minor faults to be ignored, if desired.

 

The Dynatel 2273 cable/fault locator is easy to operate and requires very little training. Digital liquid crystal display (LCD) readout and push-button operation make the unit easy to understand, for more precise locates. A “memory” feature remembers operator set-up from previous use.

The system consists of three basic components:

  • Transmitter with built-in ohmmeter, which also senses and measures the presence of foreign voltage, and tests the continuity of the circuit.
  • One-piece hand-held receiver with bar graph that indicates received signal and proximity to the cable.
  • Earth contact frame that is color-coded to correspond with indications from the receiver directing the operator toward the fault.

The 2273 cable/fault locator uses four active trace frequencies — 577 Hz, 8 kHz, 33 kHz and 200 kHz — which can be used individually or simultaneously to compensate for varying field conditions. It also incorporates one passive trace frequency — 50/60 Hz power (userselectable) — which does not require the use of the transmitter.

Both the receiver and the transmitter feature a self-test routine which is executed each time the unit is turned on. A power-up battery test indicates the battery level. Both components are constructed of heavy-duty materials designed to withstand typical field use.
