Classification of partial discharges
IEEE Transactions on Electrical Insulation, 1993 For a long time, classification of partial discharges was performed by eye, by studying discharge patterns at the ellipse of an oscilloscope screen. The introduction of digital processing techniques allowed automation of the recognition procedure. These procedures are reported and applied to a number of actual HV constructions which suffer from partial

Localization of Partial Discharges in Hydrogenerators by Ozone Emission
EnergiesWe suggest a new method of localization of partial discharges in high-power electrical systems. Ozone in a hydrogenerator is produced by chemical reactions induced by partial discharges in the stator region.

Study power of partial discharges to voltage intensity in XLPE-insulated cables [PDF]
Омский научный вестник, 2020 The article investigates partial discharges (PD) as a mechanism of insulation destruction. Some of the known mathematical models of insulation aging take into account the effect of partial discharges. These models are based on the dependence of partial

Partial discharge Source Calibration of Radiated Partial Discharge Signals
2022 2nd International Conference on Advance Computing and Innovative Technologies in Engineering (ICACITE), 2022 Based on the IEC 60270 guideline, a galvanic quantification along with free-space radiometry (FSR) method are used to measure partial discharge (PD) simultaneously. The PD source is a floating-electrode emulator type that was custom built. Sources are powered by AC or DC, power supplies. A biconical antenna captures the emitted a signal.
