Purpose of the development: To determine the distance to the fault location of the power supply cables.

Recommended application field: In maintenance of power supply cables.

Technical characteristic: Maximum measured distance to the fault location, km -16.4 * (35 **) * with a shortening factor of 1.87 for power cables ** by individual order, without changing the cost of the device. The minimum measured distance to the fault site, m - 3 Measurement resolution, m - 0,5 Parameters of high-voltage probing pulses at a load of 30 Ohm: amplitude, kV - from 3 to 60; duration of the front, microseconds, no more than 0,15 pulse duration, ?s, not less than - 2 range of change. gain of the input amplifier, dB from 0 to 60 Parameters of low-voltage sounding pulses at 30 Ohm load: amplitude, V, not less than - 5 duration of the front, microseconds, no more than 0.02 pulse duration, ?s, - 0,05-10 range of change. gain of the input amplifier, dB from 0 to 60 Setting range of shortening factor from 1,000 to 3,000 Screen Settings: screen size, mm 95x55 resolution of the indicator, points 210x128 The maximum operating voltage of the pulse voltage sensor, kV - 60. The reflectometer allows continuous operation for 8 hours. The operating life of the reflectometer is at least 5 years.

Advantages over analogues: The device allows you to save an unlimited number of waveforms on an external storage medium (USB-flash) or compare any two waveforms between each other during the measurement. With a connected USB-flash, the operator can compare an unlimited number of different waveforms during measurements. The device allows: Detect and determine the distance to the place of damage or inhomogeneity by the local (reflectometric) method on symmetrical and asymmetrical cables; to measure the length of cables (including on drums and in coils) or the distance to the places of breakage or short circuit; store, store and process measurement results; as part of a mobile laboratory to determine the distance to damage in cables up to 15.3 km (35 km) in all types of damage without the use of a preliminary complete burning of insulation.
