  • It’s capable of performing range and speed measurements with precision;
  • It ensures that no discharge waveforms are missed, thanks to its continuous and automatic sampling feature;
  • The Cable Fault Pre Locator employs various testing methods such as the low voltage pulse technique, high voltage flashover approach, and multiple pulse testing;
  • It offers substantial waveform storage, allowing for easy on-site recording and later review of test waveforms in a designated sequence;
  • The screen can concurrently display both the waveform at the fault point and the full-length open circuit waveform of a good phase for direct and overlay comparison, aiding in more precise fault location;
  • With a built-in li-polymer battery, it provides over four hours of continuous operation after a full charge, is perfectly suited for field testing, and can also be used with an external power source;
  • It automatically presents the full array of pulse transmission and fault reflection signals, along with the complete waveform of an open circuit cable, simplifying the identification of fault characteristics. It identifies high-resistance faults with a waveform similar to short circuits in low-voltage pulse tests, providing an automatic display of fault distance without any testing blind spots.
