Детали о продукции

We are engaged in manufacturing excellent quality TDR Cable Fault Locator RI-407 in Saint Petersburg, Sankt-Peterburg, Russia.

Application Area
RI-407 is intended for the following measurements on balanced and unbalanced cables:
a c cable length measurement and cable continuity tests;
a c measurement of the distance to the heterogeneity of the cable impedance or low-resistance fault, using the pulse (TDR) method;
a c measurement of the distance to the high-resistance fault, using the Arc Reflection Method (ARM) in complex with the high-voltage pulse generator (HVPG);
a c measurement of the distance to the high resistivity fault, using the Impulse Current Method (ICM) or Decay Method in complex with the high-voltage pulse generator (HVPG);
a c measurement of the velocity factor of the line at a known length;
a c determination of faulta s nature;
a c recording into internal storage and playback of at least 300 waveforms for subsequent processing in stationary conditions;
