A laboratory specializing in on-site testing of underground and submarine high-voltage cables before commissioning. Tests are performed on completed installations before they are connected to the grid, in order to verify the condition of cables and their accessories and ensure reliable operation throughout their service life.
The testing services include low-voltage checks, such as conductor and screen resistance, line impedance, capacitance, and grounding verification, as well as high-voltage tests, including dissipation factor (tan delta), partial discharge measurements, and withstand voltage tests. Voltage is applied using the WRV 260/80 resonant test system.
The laboratory has more than 15 years of experience and has tested over 700 three-phase circuits across multiple countries in Europe and Latin America.
