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.

Different from a conventional partial dischargemeasuring set provided with a fixed testingfrequency, Model DAC-PD-5 is newly designed toselect the center and the bandwidth of testingfrequencies so that partial discharges emitting in anoptional frequency in the range of a specifiedbandwidth can be detected. Generally, partialdischarges are measured in a wide band frequencythough; the detecting sensitivity must be lowered inorder to detect partial discharges partially.DAC-PD-5 has a wider bandwidth and can measurepartial discharges in a high sensitivity by bypassingnoises emitting bands.
