The combined laboratory up to 35 kV (ETL-35K) consists of:
1. Test facility
• – Maximum rectified voltage up to 70 kV;
• – Maximum AC voltage of the industrial frequency of 50 Hz to 100 kV.

2. Insulation parameters meter
• – Transformation coefficient;
• – No-load losses at low voltage;
• – Short circuit resistance;
• – Voltage and current;
• – Power factor;
• – Frequency of the measured voltage (current);
• – Phase shift angle between voltage and current;
• – Measurement of the active resistance of the windings.

3. Burning facility
• – Maximum voltage up to 30 kV;
• – Maximum current up to 80 A;
• – Working hours are not limited;
• – Switching of stages is carried out without breaking the arc at the time of switching;
• – The ability to start working from any stage of burning (when working with low-voltage cables);
• – Built-in afterburning.

4. High voltage pulse generator
• – Output voltage 0...12 kV / 0...24 kV;
• – The pulse energy at each stage is 3000 J;
• – Built-in IDM for collaboration with the reflectometer.

5. Reflectometer
– Supports 3 methods of determining the location of damage:
• – By pulse reflectometry;
• – By the method of oscillatory discharge;
• – Pulse-arc method.

6. High-voltage cable defects detector
• – Determining the location and depth of the cable at a depth of up to 10 m;
• – Tracing at a distance of up to 10 km;
• – Search for live electrical cables;
• – Search for places where pipelines and cables intersect;
• – Determining the places of damage to cable lines;
• – Site surveys before excavation;
• – Search for places of damage to the external insulation of the cable;
• – GPS\GLONASS coordinates recording and mapping of found communications;
• – Cable selection from the bundle;
• – Search for the place of damage by acoustic method.
