Three-phase reflectometer RIF-9 is designed for quick and efficient fault pre‑location and distance measurement in electrical power cables and communication lines up to 120 km long.
High-voltage methods (when combined with a surge wave generator / thumper in ETL cable test van or SWG mobile cable test and fault location system)
RIF-9 features three measurement channels allowing to display reflectograms from one, two or three cable phases at once in the time-domain reflectometry (TDR) mode.
This feature makes it possible to analyse and compare the different cable phases, which may be especially useful when identifying a particular failed phase or detecting low-resistance faults.
RIF-9 is equipped with ARC multi-shot technology, which allows to send up to 15 probing pulses per single surge generator discharge. This function simplifies prelocation in ARC mode by increasing the chance of obtaining a high-quality reflection off a flashover arc at the place of a fault.
Large 10.4" TFT colour display with touch control makes menu navigation, data entry and general device control easy and intuitive. High brightness and rich colour reproduction provide good visibility both in direct sunlight and in the dark.
RIF-9 automatically analyses the obtained reflectogram and sets the cursor as necessary at the end of the cable or at the fault.
The instrument is also capable to analyse the reflectogram and automatically characterise the fault aiding the operator in the cable line maintenance.
Up to 1000 parameterized reflectograms and up to 500 cable shortening ratio values can be stored in the RIF-9 memory. Saved reflectograms can be uploaded or copied to an external USB drive which can also be used to update the system firmware.
Connection cables can be excluded from the final reflectometry measurements.
The measuring cables length is automatically subtracted from the obtained length of the measurement object, making it possible to see only the curve that matters.
A table with shortening coefficients for various cables may be stored in the RIF-9 memory. To optimize subsequent measurements, an operator can select the required parameters, edit data and upload the list of cables from an external USB drive.
