5250 Series Portable Cable Fault Locating Systems - Overview

Haefely Hipotronics'  5250 Systems meet the demanding needs of utilities, industrials, and contractors who require a highly portable, easy to use, complete fault locating system. The 5250 system utilizes the most innovative TDR techniques; along with the highest energy, battery operated portable compact thumper the market has to offer.

These systems will reduce your fault location time by up to 80% allowing quick and easy sectionalizing of fault loop feed URD installations without disconnecting transformers and provide fast fault location in underground cables. Isolation of a cable fault between two transformers is easily identified.

The 5250 battery powered cable fault locator combines a high voltage filter, digital high voltage TDR and battery charger into one complete, easy to use, cost-effective package. Operation of the entire system is done from the controls of the TDR1150, or manually from the 5250 control panel. Connection to the cable under test is easy with quick clamp connectors on an HV output cable.

Once the 5250 is connected to the cable under test, a trained operator will be able to find faults in a matter of minutes. The digital TDR1150 allows built-in storage of waveforms. In addition, the 5250 TDR1150 has a built-in serial port to allow an operator to download waveforms to a computer for evaluation or long-term storage.
