Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

High Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

Mechanism on improved surface flashover performances in vacuum of epoxy resin using fluorocarbon plasma treatment

High Voltage, 2022
To improve the insulation, strength of materials is a permanent topic in the fields of high voltage and insulation, and surface insulation is one of the difficulties. Research shows that the surface fluorination by a non‐equilibrium plasma is a promising

Fabrication and operation of a two-dimensional ion-trap lattice on a high-voltage microchip [PDF]

, 2014
Microfabricated ion traps are a major advancement towards scalable quantum computing with trapped ions. The development of more versatile ion-trap designs, in which tailored arrays of ions are positioned in two dimensions above a microfabricated surface,

The Reaction‐to‐Fire Performance of Intumescent Coating After Ageing by Thermal and Moisture Exposure

Fire and Materials, Volume 50, Issue 3, Page 318-333, April 2026.
ABSTRACT Materials and products age with time and their properties change. It is known that, for example, the mechanical strength may be deteriorated from ageing. To understand the ageing effect on the fire behaviour of materials and products is important to maintain the safety level of the construction or application.

Lightning‐caused disturbance frequency and severity varies with topography in an Afromontane forest

Journal of Ecology, Volume 114, Issue 3, March 2026.
The results indicate that lightning disturbance severity differs within and among sites, potentially mediated by differences in lightning tolerance among tree species, and provide preliminary support for the hypothesis that disturbance severity declines with disturbance frequency. Abstract Lightning is an important agent of tropical tree mortality, but

The effect of dynamic behaviours of the water droplet on DC/AC flashover performance on silicone rubber surface: Experiment, simulation and theoretical analysis

High Voltage, 2021
It is usually seen that DC flashover voltage of the water droplet on the surface of silicone rubber (SIR) composite insulator is lower than AC flashover voltage.

Spectral Characteristics and Evolution Mechanism of Silicon Rubber Surface Discharge Under Thermal Ageing Condition

High Voltage, Volume 11, Issue 1, Page 192-200, February 2026.
ABSTRACT Surface discharge is a typical fault type in electric power equipment. High temperature in long‐term operation can easily lead to ageing of materials, resulting in changes in surface characteristics and surface discharge faults. In this paper, a method of surface discharge identification of silicon rubber (SiR) based on spectral detection ...
