A time scale for electrical screening in pulsed gas discharges [PDF]

, 2014
The Maxwell time is a typical time scale for the screening of an electric field in a medium with a given conductivity. We introduce a generalization of the Maxwell time that is valid for gas discharges: the \emph{ionization screening time}, that takes ...

Study on the Effect of Void Geometry and Location on Electric Field Distribution and Partial Discharges in HVDC Cables [PDF]

E3S Web of Conferences, 2023
Nowadays HVDC transmission systems are preferred over HVAC systems because of their less power loss and high reliability. In the HVDC cable transmission system, there is a problem of Partial Discharges (PD) occurring due to cavities of the dielectrics in

Method of fault‐type recognition based on the dissolved gas analysis using a set of diagnostic criteria

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.
