Partial discharge measurement with remote wireless reading
PD-LT
The PD-LT allows online partial discharge detection on cable accessories such as cable head for safety and maintenance purposes.The PD-LT 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 medium voltage accessory.The remote display gives a dB value of the probe's measurement. The dB value will vary along with the discharges indicators on the PD-LT probe. The measurement range is from 0 to 65dB and the display will show ''OL'' if the reading is over 65dB.

Cable Identification & Phasing
VCi-3™
The VCi-3™ system is designed for cable and phase identification, mainly for installation or maintenance purposes on three-phase electrical networks during power shutdowns.The transmitter module injects a low current on the cable conductors by direct contact or magnetic clamps methods. A voice message is recorded by the user and will be transmitted along with digital signals. Groundings stay connected at both ends of the three-phase circuit during the test. The detector module is used at the other end of the cable system.
