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

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.

Modeling partial discharge phenomena
IEEE Electrical Insulation Magazine, 2020 Measurements of partial discharge (PD) activity are a commonly used technique to diagnose the health of insulation material within high voltage plant. The definition of PD is relatively broad, it is generally defined as a localized or confined discharge within an insulating medium [1]. Due to the high electric breakdown strength of insulation materials,

Partial discharges characteristics study in XLPE cable insulation with multiple defects [PDF]
Омский научный вестник, 2021 The paper simulates the electric field intensity picture in the cable with one and several defects. Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with

IET Generation, Transmission & Distribution, 2023 This paper proposes a method for recognising the fault type using a set of diagnostic criteria. Existing approaches to the interpretation of dissolved gas analysis (DGA) results usually rely on single diagnostic criteria.
