Alexandria Engineering Journal, 2022 This paper proposes a novel two-stage adaptive reclosing mechanism for shunt-compensated extra-high-voltage transmission lines. In the first stage, secondary arc extinction peak-based criterion (SAEPC) is established to monitor the precise instant of ...

Secondary Arc Extinction in Extra High Voltage Systems Using Grounding Switches
Diyala Journal of Engineering Sciences, 2014 Long Extra High Voltage (EHV) transmission systems tend to bring a pronounced state of secondary arcing. Therefore, an essential pre-requisite for single-phase-switching application, is the possibility and speed of secondary arc final extinction during ...

Numerical Modeling of Space–Time Characteristics of Plasma Initialization in a Secondary Arc
Energies, 2019 A numerical model based on the finite element simulation software COMSOL was developed to investigate the secondary arc that can limit the success of single-phase auto-reclosure solutions to the single-phase-to-ground fault.

Modelling of Secondary Arc Using EMTP-RV [PDF]
The Transactions of The Korean Institute of Electrical Engineers, 2012 Most of faults occurred in transmission lines are single-phase to ground faults and transient faults. Single-phase auto reclosing is an appropriate scheme to maintain the system stability and restore the system effectively when those faults are occurred.
