Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

open access: yesHigh Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

open access: yesHigh Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

Diffusion of Characteristic Gases in Oil‐Immersed Transformer by Computational Fluid Dynamics Simulation and Experimental Verification

open access: yesHigh Voltage, EarlyView.
ABSTRACT The complex diffusion of characteristic gases within oil‐immersed transformers significantly influences the timeliness between the fault occurrence and gas detection. So far, the gas transport processes and spatio‐temporal distributions remain inadequately understood.
