TDR.650 Time Domain Reflectometer
Introduction to the TDR.650:

  • This cable fault locator is designed for ease of use, portable, lightweight, and easy to carry.

​

  • It uses the time domain reflectometer (TDR) for measuring the exact fault location such as broken lines, cross faults, earthing, poor insulation, and poor contact of lead-covered cables as well as plastic cables.

​

  • By setting the proper wave velocity, just pressing the Auto key will provide the test result within 2 seconds.

​

  • It is an effective tool to reduce troubleshooting time, improve work efficiency, and reduce labor intensity for line maintenance staff. It can also be used for line projects' acceptance and inspection of electrical cables.
