IRG 2000 Time Domain Reflectometer


The Pulse Reflection Test Set IRG 2000 is a portable, easy to use, single-phase unit for cable fault pre-location using time domain reflectometry (TDR) method on low, medium, and high voltage cables. It can also be used on live cables up to 400 V. Further fault location methods are available with the application of the appropriate coupling device. Its measuring ranges enable pre-location on cable lengths from 0 m to 65 km (0 to 213,000 feet).

The IRG 2000 is operated via function keys and is fully menu guided. The LCD color screen allows up to three waveforms to be displayed at the same time. The unit is supplied with rechargeable batteries and can also be powered directly by mains supply.
