Low-voltage method for fault detection, Time-Domain Reflectometry (TDR), is crucial for pinpointing low-resistance faults and breaks in power cables and communication lines. High-voltage methods like ARC and ICE help locate high-resistance faults effectively. Utilising surge wave generators enhances fault location accuracy.

RIF-9 offers three measurement channels to show reflectograms from one, two, or three cable phases simultaneously in time-domain reflectometry (TDR) mode. This capability enables thorough analysis and comparison of cable phases, aiding in the identification of failed phases or detection of low-resistance faults, enhancing troubleshooting efficiency.

RIF-9 introduces ARC multi-shot technology, allowing the transmission of up to 15 probing pulses with every surge generator discharge. This streamlines prelocation in ARC mode, increasing the chances of capturing a high-quality reflection from a flashover arc at the fault location. Optimize your fault location with RIF-9’s advanced ARC multi-shot technology.

The 10.4-inch TFT colour display with touch control simplifies menu navigation, data entry, and device control. Its high brightness and rich colour reproduction ensure excellent visibility in both sunlight and low-light conditions. Opt for this user-friendly display for easy device operation and clear visuals in any environment.
