IRG 4000 Time domain reflectometer

The IRG 4000 is integrated in BAUR cable fault location systems and is used in combination with the system software for locating cable faults in single and three-phase cable systems.

Manufactory: BAUR (Austria).

Features
  • Automatic detection of cable end and fault position
  • Automatic saving of all measurement data
  • Storage for more than 100,000 measurements
  • Interface to GIS databases
  • Voltage-proof up to CAT II/600 V
  • Can be combined with BAUR cable testing and diagnosis systems (for installation in the cable test van)
