The computer aided pulse reflection test system IRG 3000 is the basic control unit for all cable fault location methods. It is specially designed as a pulse reflection measuring instrument for fault location on single and three-phase cable systems. Latest generation technology is implemented in the expert system, with an integrated 200 MHz transient recorder for the highest measuring accuracy. It offers unique features for intelligent manual and automatic cable fault location.
The windows-based software allows every user easy and fast operation of the system. Up to three cable fault location methods can be displayed at the same time on the TFT-LCD display. The high resolution and zoom function enable accurate pre-location of cable faults. The design of IRG 3000 has set new international standards in automatic cable fault location.
Features
- Fully automatic measuring sequences
- Fully automatic cursor settings
- 3 phase measurement and display
- Memory for > 100,000 waveforms (hard disk limit)
- TDR output pulse from 20 to 160 V
- 200 MHz real time transient recorder with high resolution
- Measuring ranges up to over 200 km
Measuring methods
- Time domain reflection method - single or multicore
- Secondary impulse method/ multiple impulse method (SIM-MIM) - advanced SIM with SA 32 coupler
- Secondary impulse method, SIM DC - with SA 32 coupler
- Differential secondary impulse method - with SA 32 coupler
- Impulse current method - with SK 1D inductive coupler
- Decay method - with CC 1 apacitive coupler
- Differential impulse current method - with SK 3D inductive coupler
- Differential decay method - with SK 3D inductive coupler
Options
- MΩ - fully automatic three phase selection by software
- Control software with the PHG very low frequency (VLF) test system
- Control software with VLF cable diagnostic system, including dissipation factor and partial discharge measurement
The IRG 3000 offers the possibility of upgrade to a diagnostic system. The very low frequency sinusoidal high voltage generator - PHG, the dissipation factor measuring system - TD, and partial discharge measurement/ location systems can be added to the IRG 3000 at a later stage to make it into a test and diagnostic system - PHG TD/PD.
