Cable Fault Location | High Performance Time Domain Reflectometer (TDR)

Cable Failure Testing of Power Cables, Coaxial Cables, Data Cables and Communication Cables

High accuracy waveform and numeric cable fault TDR locators used to locate failures within a cable.


Waveform type BTR5000 and handheld BTR1000 models are designed to rapidly identify and locate faults in all types of metal cables such as power, electric, telecom, transportation, and environmental.


BTR5000 model is an advanced instrument capable of identifying a wide range of cable faults with a testing range of 50cm ~ 20,000m / coaxial.


Waveform cable fault locator TDR has tracible memories, which allows previous test results to be recalled for preventive analysis and to evaluate the degradation of the same cable over time. The collected data can be transferred to a computer, for analysis and storage for future references.


Both models are housed in a rugged, robust, field proven case making it suitable for use in challenging environments.

Time Domain Reflectometer TDR Advantages | Cable Fault Finder TDR

Time Domain Reflectometers are industry’s most accurate, quick, and reliable testing units for safe pre-location of cable faults in electrical networks.

LPR Global’s TDR units are designed to locate faults, opens, taps shorts, blockages, resistance in electric cabling, as well as connector locations and overall cable length. Common cable faults include screening faults, phase faults, contact between multiple conductors, signal loss, sheath faults, crushes and breaks, and moisture or cut cable related faults.


We offer two TDR models BTR 5000, larger portable advanced model and BTR1000, handheld time domain reflectometer which are used for fault location in all metal cables such as power cables, coaxial cables, twisted pair, parallel pair, data cables and communication cables.


BTR5000 TDR sends a quick voltage pulse down the cable under test and recognizes any detected impedance abnormalities. TDR cable tester measures the time it takes for the pulse to return, this way revealing the location of the fault in the cabling system displaying the waveform amplitude of the signal connection. Once this information is collected and analyzed, it is stored and can be recalled to evaluate the degradation of the same cable over time and for cable fault preventive analysis.

Cable Fault TDR Locator BTR5000

Waveform type TDR. Displays the outgoing pulse and any reflections which are caused by impedance changes along the length of the cable on the LCD display. Used for detecting smaller faults and for long distance cable testing.

Numeric Cable Fault TDR Locator BTR1000

Numeric type TDR indicates the distance to the first major reflection caused by a fault along the cable. Allows to detect if the fault is an open or short and power loss.

High accuracy BTR5000 and BTR1000 models feature an automatic set-up, equipped with dual trace and step function which can be modified as necessary. All fault data can be stored internally and retrieved for comparison.


Waveform and Numeric TDR Cable Fault Locator Usage Applications

  • Troubleshoot all power supply measurements: connection, change of cable type, break in the cable
  • Landline preventative maintenance
  • Operation surveillance: trace cables to identify runs, wiring faults and the distance to them
  • Determine length of cables
  • Determine degradation of cables due to moisture and dust
  • Test patch cords
  • Test for active service
  • Map network layout
