Laboratorio elettrico "ANGSTREM" (ETL-10, ETL-20, ETL-35)

Electrotechnical laboratories of production of LLC ANGSTREM allow to solve a full complex of tasks on testing, diagnostics and searching for places of damage to underground cable lines of voltage classes 0.4, 6, 10, 20, 35 kV with any type of insulation. Purpose: Testing substation equipment. Tests of underground cable lines with any type of insulation. Determination of the distance to the damage of power cables using the most modern and efficient methods: method of reflected pulses pulse-arc method, stress wave method current wave method. High-precision detection of damage to underground cables by induction, acoustic, acoustic-electromagnetic and potential methods. Inspection of the terrain and the search for communications routes and cable lines, including those with a voltage of 50 Hz. Determination of the depth of underground utilities. Select a specific 1-phase or 3-phase bundled cable. Burning of places of damage to the insulation of power cables. Measurement of high voltage insulation parameters. Measurement of parameters of power transformers at low voltage. Diagnostics of the state of insulation of power cables by measuring partial discharge parameters at ultra-low frequency.
