PDS - Partial Discharge Scanner

The PDS allows online partial discharge detection on underground cable accessories and equipment for security/maintenance purposes. This equipment is perfect for a high voltage predictive maintenance program. The PDS is very accurate to detect partial discharge on cable joints (XLPE/EPR type).


Insulation faults are an important factor in degradation and reduction of the lifetime of an electrical joint. This translates into raised exploitation costs and questionable reliability, while economic performance and reliability are key criteria in the evaluation of an electricity supplier. It is important that an electric utility have a widespread, quick and efficient tool to check for quality and health of its electrical network.

The market's demands on electric utilities necessarily transfer to their subcontractors, who must comply with higher quality requirements for their work. Like the electric utility for which he works, the subcontractor that has tools allowing him to monitor and to certify the quality of his job will become an attractive and reliable choice.

Even if you are from an electric company or a subcontracting firm, the question remains simple: Are we reliable, thus competitive? The PDS answers this question, short and simple. No conversions, no interpretation: only the answer to the question with which you are most concerned, free from all the useless data.

The PDS indicates the intensity of the partial discharges, converting the electrical charge units (pC) into decibels (dB). Thus, the reading is kept as a simple intensity level indication, proportional to the probability of a fault's presence in the tested joint. The visual indicator is a bar graph with eight steps, each step corresponding to twice the intensity (6dB) of the previous level, for a total range from 6dB to 54dB. An audio indicator, the frequency of which is proportional to the displayed intensity, allows the user to locate any fault even if the handling conditions do not allow him/her to see the display.

Small to ease access to all types of installations, the PDS can be handheld or manipulated with a hotstick depending on the situation. Obviously, along with strippers and insulated tools, it belongs in one’s toolkit, for everyday work.
