  • High sensitivity capacitive sensors with wire less measurement readings
  • Compact, lightweight and battery powered for maximum flexibility
  • Suitable for use in isolation network components
  • Easy and safe to use with a hotstick

Insulation faults are an important factor in degradation and reduction of the lifetime of a medium voltage component. 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. 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 PD-LT™ allows online partial discharge detection on cable accessories such as cable head, lightning arrestors, insulators, bushings, for safety and maintenance purposes. The partial discharge level is displayed on the remote display.

The measurement range is from 0 to 65dB and the display will show ‘‘OL’’ if the reading is over 65dB.
