Online Partial Discharge Scanner
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.
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.
There is a LED indicator on the device. In this way, up to 54dB measurement value can be displayed visually. In addition, depending on the measured value, the user is given a partial discharge level as a result of the measurement.
Trending evolution is important in the partial discharge monitoring. It is suggested to measure every cable joint/elbow at least once a year, and to note the levels in order to create a trending evolution study.
Through it is small size, PDS™ is easy to transfer and use. It can setting up on hotstick and can be used easily even in cable layouts which are difficult to reach.
