ISKRA-4 time domain reflectometer

ISKRA-4 time-domain relectometer TDR


High-voltage oscillographic reflectometer "ISKRA-4" is designed for distance fault locations of communication and power supply cables.

The device allows:

  • to detect and to find the distance to the damage or discontinuity place by using the location (reflectometric) method for symmetrical and asymmetrical cables;
  • to measure the length of cables (including that in reels and coils) or the distance to the spot of rupture or short circuit;
  • to save in memory, to store and to process the measurement results;
  • as a part of test vans or SWGB, to find distance to the damage in cables up to 15,3 km long by all kinds of damages without using complete insulation per-burning.

* at the request of the customer modification is possible with a distance of up to 35 km

 Measuring methods for distance fault locations :

    • TDR;
    • ARC**;
    • ICE**;
    • Decay**.

**together with SWGB or test vans

In addition, the reflectometer provides operation with various arc stabilization devices, to measure the distance to the fault location of power supply cables.

The device allows you to save an unlimited number of reflectograms on an external storage medium (USB flash drive) or compare any tworeflectograms between each other during the measurement. With the connected USB flash drive, the operator can compare an unlimited number of different reflectograms logs during the measurement.

Attention! Processing of the saved reflectograms on the computer is performed with the help of a special program, which is transmitted to the consumer taking into account his requirements for working with the program.
