Physicochemical Properties and Molecular Dynamics Simulation of Composite Insulators in Regions with Intense Ultraviolet Radiation

open access: yes工程科学学报
In high-altitude areas, high-intensity ultraviolet (UV) radiation can induce changes in the molecular structure of silicone rubber, thereby leading to significant aging of composite insulators, ultimately resulting in insulation performance failure ...

Analysis of Defect Detection for 10 kV Composite Insulator Based on the Microwave Method

open access: yesEnergies
During the long-term operation of composite insulators in transmission lines, they are easily affected by harsh environments, resulting in hidden defects such as surface contamination, shed damage, and adhesive failure. A defect detection method based on

Detection of Hydrophobicity Grade of Composite Insulators Based on MDC‐YOLO Algorithm

open access: yesEnergy Science & Engineering
In the field of power equipment inspection, the aging condition of composite insulators is often determined by the detection of water repellency. However, the existing detection methods are difficult to effectively extract the water repellency level ...

Specific Position and Influence of Moisture in Newly-Installed Composite Insulators

open access: yesCSEE Journal of Power and Energy Systems
Abnormal heating of composite insulators is a hidden threat to safe operation of transmission lines. Although moisture is considered the key factor leading to temperature rise in high humidity areas, specific position and diffusion path of moisture are ...

Dependence of the Metal–Insulator–Semiconductor Schottky Barrier Height on Insulator Composition

open access: yesACS Applied Electronic Materials
The effects of different high-κ tunnel oxides on the metal-insulator-semiconductor Schottky barrier height (ΦB) were systematically investigated. While these high-κ interlayers have been previously observed to affect ΦB, there has never been a clear consensus as to why this ΦB modulation occurs.
