SFX 15 & 25 Mobile, Battery Operated Cable Fault Locating System

The Surgeflex 15 and 25 cable fault location systems with their 1150 J surge energy provide a standard solution for portable systems.

The basic system comes already fully equipped with integrated battery, inverter/charger and is mounted on an easy to move trolley. For a fixed vehicle mounting, the systems are also available without trolley and internal battery system.

For high flexibility, the systems are equipped with a separately mounted reflectometer cum controller. With the ARM Arc Reflection Method, a powerful tool for the fault location, especially for highly resistive faults is available.

Key benefits:

  • Easiest operation
  • ARM and ICE integrated
  • Very compact and rugged design
  • Battery operation up to 4 hours
  • Weather proof stainless steel housing

Complete fault locating system with:

  • DC-Testing up to 15 kV / 25 kV (depending on model)
  • Prelocating
  • Reflection measurement
  • ARM-Measurement (Arc reflection method)
  • ICE Impulse current method
  • Cable tracing (optional)
  • Pin-pointing
  • Distance and acoustic measurement
  • Audio frequency methods (optional)
  • Battery and mains operation
