Offline Testing on Power Cables
High-voltage cables are used for supplying power in densely-populated areas or for example to off-shore installations. Trouble-free operation over decades with little or no maintenance is therefore a requirement to ensure a secure energy supply.
The diagnostic possibilities for assessing the condition of power cables and cable accessories include partial discharge tests for assessing the condition of the cable insulation. Additional diagnostic tests for determining the condition of power cables include capacitance, power/dissipation factor and dielectric response measurements.
