We conduct pd diagnostic testing on cables (up to 35 kv). Partial discharge is an is an electrical discharge or spark that bridges a small portion of the insulation between two conducting electrodes.
Partial discharge activity is the first idication of insulation faults which could serve as a warning for a potential degradation of the insulation in the medium and high voltage cables. Partial discharge has become an established method in commissioning new assets or used as condition based assessment of used cable systems.
We utilize megger’s dac systems technology, slope 50/60 hz technology or the vlf cr as well as vlf sinus.
