Study of DC partial discharge on dielectric surfaces: Mechanism, patterns and similarities to AC

Autor: Armando Rodrigo Mor, Saliha Abdul Madhar, Robert Ross, Petr Mraz

Publikováno v: International Journal of Electrical Power & Energy Systems, 126

This paper presents the investigation on surface discharge behavior of various dielectric samples under DC. It sequentially develops the knowledge base for the study and analysis of the partial discharge (PD) defect with the goal of PD defect identif

Measurement of key dielectric properties for surface PD model under HVDC

Autor: Petr Mraz, Marc Brunner, Armando Rodrigo Mor, Saliha Abdul Madhar

Publikováno v: Proceedings of the 2020 IEEE 3rd International Conference on Dielectrics, ICD 2020

The discharge over dielectric interfaces popularly known as surface discharge is a very common defect type that is associated with its respective discharge pattern under AC voltages. However, the same designs behave differently under DC voltages lead

Empirical analysis of partial discharge data and innovative visualization tools for defect identification under DC stress

Autor: Robert Ross, Petr Mraz, Armando Rodrigo Mor, Saliha Abdul Madhar

Publikováno v: International Journal of Electrical Power & Energy Systems, 123

This paper presents several approaches to the analysis of partial discharge (PD) data. Three common defects namely corona, surface and floating electrode are studied with the goal of defect identification under DC stress conditions. One of the major

Guidelines for PD measurement according to IEC 60270

Autor: Petr Mraz, Saliha Abdul Madhar, Patrick Treyer, Urs Hammer

Publikováno v: 21st International Symposium on High Voltage Engineering, Budapest, Hungary, August 26-30, 2019
Delft University of Technology

Partial discharge measurements performed according to IEC 60270 has become an essential tool for the quality assurance of HV equipment. The main goal of IEC 60270 is to standardize and unify PD measurements to get comparable results for tests perform
