Description
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 SVPA, 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;
- ICE**;
- Decay**.
**together with SVPA 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 two reflectograms 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.

Technical data
High-voltage oscillographic reflectometer ISKRA-4
Measuring methods – TDR, ICE, Decay;
Distance-finding range to cable damage place – from 3 m to 15300 m *;
Measurement resolution – 0,2 m.
* at the request of the customer modification is possible with a distance of up to 35 km
Parameters of high voltage monitoring pulses at a load of 30 Ohm:
- range – from 3 to 25 kV;
- acceleration time, max. – 0,15 µs;
- pulse duration, max. – 2 µs.
Parameters of low-voltage monitoring pulses at a load of 30 Ohm:
- range, min. – 5 V;
- acceleration time, max. – 0,02 µs;
- pulse duration – 0,05-10 µs.
Maximum operating voltage of the pulse voltage sensor – 60 kV.
Measurement error of the distance to the damage place at high voltage depends on the measurement mode and on the breakdown voltage of the damaged section.
The reflectometer allows continuous operation for 8 hours.
