Partial Discharge Testing Equipment
AR700
-
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.

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.
