Partial discharge pulse propagation in power cable and partial discharge monitoring system [PDF]

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 2014
Partial discharge (PD) based condition monitoring has been widely applied to power cables. However, difficulties in interpretation of measurement results (location and criticality) remain to be tackled. This paper aims to develop further knowledge in PD signal propagation in power cables and attenuation by the PD monitoring system devices to address ...

Partial Discharge Behaviour within Two Spherical Cavities in a Dielectric Material [PDF]

open access: yes, 2011
In high voltage insulation systems, a typical defect that exists is a void cavity. It is known that voids are a common source of partial discharge (PD) activity within an insulation system.

DEVELOPMENT AND CALIBRATION OF A MICROCONTROLLER BASED PARTIAL DISCHARGE CALIBRATOR

open access: yesElectrica, 2016
Partial discharge is an instantaneous energy release depending on a charge accumulation caused by an electric field localized in any section of insulation materials. In this phenomenon, there is no observation of full discharge but electrical perforation

Classification of partial discharges

open access: yesIEEE 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
