Research on discharge phenomenon caused by cross‐adsorption of linear insulating fibre and metal dust under DC voltage

High Voltage, 2022
A large amount of metal dust is often generated during production and operation of Gas Insulated Switchgear/Gas‐Insulated Transmission Line, and insulating fibres are very easy to mix in during assembly.

Impact of Air Gap Defects on the Electrical and Mechanical Properties of a 320 kV Direct Current Gas Insulated Transmission Line Spacer

Energies, 2023
Air gap defects inside a spacer reduce its insulation performance, resulting in stress concentration, partial discharge, and even flashover. If such gap defects are located at the interface between the insulation and conductor, a decrease in mechanical ...

Modeling of Electromagnetic Fields Along the Route of a Gas-Insulated Line Feeding Traction Substations

Energies
Power supply for traction substations (TSs) of AC railways has traditionally been provided by 110–220 kV overhead transmission lines (OHL). These OHLs can be damaged during strong winds and ice formation.

Tailoring of electron flow current in magnetically insulated transmission lines

Physical Review Special Topics. Accelerators and Beams, 2009
It is desirable to optimize (minimizing both the inductance and electron flow) the magnetically insulated vacuum sections of low impedance pulsed-power drivers. The goal of low inductance is understandable from basic efficiency arguments. The goal of low
