Modernization is intended to increase the capabilities of old cable test vans. Modernization consists in installing new equipment with full integration with existing systems.
After modernization, the following options will be added:
Testing insulate XLPE, PE, EPR, PILC power cables, etc. VLF or DC voltage according to VDE standards. IEC and IEEE (together with AV-50 / 70VLF).
Insulation tests using a 50 Hz sinusoidal voltage (together with AV-50 / 70VLF).
Determining the distance to the place of cable fault with methods: TDR, ARM, ICE and Decay (together with Iskra-4).
Determining the locations of cable faults using the acoustic method (together with Poisk-2016).
TDR-109 is a high-precision 3-channel digital reflectometer designed to determine the distances to all types of faults in the power cable lines: open, short, sleeve, cable splice, parallel branches, wet cable, high-resistance faults, intermittent breakdown and etc.
TDR-109 provides the following measurement methods:
Designed to finding high resistance faults using ARM, ICE methods in complex with reflectometr, significantly enhances their ability to detect defects with high resistance , beyond the localization of low-voltage TDR method.

The device AV-20-01 is designed for testing medium voltage cables up to 10 kV with insulation of all types.
VLF method is now recognizable by the Power Industry (and is recommended by the IEEE) for testing of XLPE and FPR cables AV-20-01 cable testing for voltages in the voltage range up to and including 20kV with a maximum length of 12Km.
The VLF test generator AV-45-01T is designed for testing of XLPE, PE, EPR, PILC power cables, etc. VLF or DC voltage according to VDE, IEC and IEEE standards. In contrast to the AV-45-01, AV-45-01T has a built-in high-voltage source and can be used as a stand-alone device. The device is mobile, but it can also be installed in a car, for example when modernizing old cable test vans.
An fully automatic diagnostic bench for performing dielectric tests on personal protective equipment MSPA-40-2 is a modern device for examining electrical insulating protective gloves, shoes and boots, incl. firemen’s footwear.
The VLF cable testing system AV-50/70 VLF is suitable for testing high voltage power cable insulation and solid dielectrics rectified voltage (DC) value to 70 kV, as well as samples of solid dielectrics sinusoidal voltage (AC) value of 50 kV at a frequency of 50 Hz and the test voltage with a frequency of 0.01 – 0.1 Hz to 45 kV for voltage testing of cross-linked polyethylene (XPLE) cables according to VDE standards. IEC and IEEE
In particular, for testing the cross-linked polyethylene cables (XLPE).
