Simulation of main plasma parameters of a cylindrical asymmetric capacitively coupled plasma micro-thruster using computational fluid dynamics [PDF]

open access: yes, 2015
Computational fluid dynamics (CFD) simulations of a radio-frequency (13.56 MHz) electrothermal capacitively coupled plasma (CCP) micro-thruster have been performed using the commercial CFD-ACE+ package. Standard operating conditions of a 10W, 1.5 Torr

Study on the Discharge Characteristics along the Surface and Charge Movement Characteristics of Insulating Media in an Airflow Environment

open access: yesEnergies, 2022
The gas–solid interface of high-voltage insulating equipment is a weaker part of insulating equipment insulation, and preventing the occurrence of discharge along the surface of insulating equipment is a critical problem for high-voltage insulation. This

Development of Acoustic Emission Sensor Optimized for Partial Discharge Monitoring in Power Transformers

open access: yesSensors, 2019
The acoustic emission (AE) technique is one of the unconventional methods of partial discharges (PD) detection. It plays a particularly important role in oil-filled power transformers diagnostics because it enables the detection and online monitoring of ...

Surface discharge characteristics and influencing factors of polyimide insulations under high‐frequency sinusoidal voltages

open access: yesIET Generation, Transmission & Distribution, 2022
The high‐frequency power transformer (HFPT) has become a vital component of the power system. For HFPT insulations, surface discharge is a serious problem. Polyimide (PI) is a widely used insulating material for HFPT's. A needle‐plate electrode structure‐

Removal of organophosphorus pesticide residues from Lycium barbarum by gas phase surface discharge plasma

open access: yesChemical Engineering Journal, 2018
Highlights • GPSD plasma was successfully applied to degrade OP residues from L. barbarum. • GPSD plasma exposure didn’t induce any changes in the fruit quality. • Electrical and optical characteristics of the plasma discharge were analysed.

Finite-element analysis for surface discharge on polyimide insulation in air at atmospheric pressure under pulsed electrical stress

open access: yesHigh Voltage, 2020
A surface discharge non-equilibrium plasma model of air–polyimide under pulsed electrical stress is established, by considering the reaction of charged particles on the dielectric surface and the secondary electron emission caused by the condition that ...

Enhancing flame and electrical surface discharge resistance in silicone rubber composite insulation through aluminium hydroxide, clay, and glass fibre additives

open access: yesAdvanced Composites and Hybrid Materials
Silicone rubber (SR) is a leading polymer used in electrical outdoor insulation applications due to its superior hydrophobic characteristics. However, the low flame and electrical surface discharge resistance of SR limit its broad viability and challenge

Analysis of water level variations in the Huangzhuang reach (Hanjiang River, China) during recent years [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2020
The 2017 Hanjiang autumn flood appeared to have higher surface water levels at the same discharge rate than previously at the Huangzhuang gauging station. It is seriously impacted the flood control.
