Partial Discharge
Partial discharge (PD) is a local electrical discharge that occurs in imperfections or inhomogeneities. The partial discharge measurement is a so-called “non destructive test” to determine the quality of insulating materials. On the contrary of pure high-voltage test, th test item is not pre-damaged at low PD levels.

Partial Discharge Testing Equipment
3i
The portable multipurpose 3i device (Intellectual Insulation Indicator) is for eff ective high-voltage equipment insulation monitoring on-line. The 3i device measures and analyses partial discharges (PD). For eff ective PD measurement and noise rejection, there are two types of sensors used in the device: the acoustic sensor and the TEV sensor. Both the sensors are built into the device case, and so do not need any connection cables. The device is supplied in a strong metal case; at the faceplate there are the colored screen and two buttons: power button and function button.

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.
