High Voltage, EarlyView.ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Implications and characterization of waste glass cullet – kaolinite clay ceramics
Journal of Applied Sciences and Environmental Management, 2019 Cullet(x) reinforced ceramics (100 – x) made from Ukpor kaolinite clay by dry-pressing and fired at temperatures (T0C) for 900≥T≤ 12500C with 0≤x ≤40% wt was investigated for its ceramics application. The chemical profile of the samples (cullet and clay)

High Voltage, EarlyView.ABSTRACT Unmanned Aerial Vehicle (UAV) inspection of overhead transmission line composite insulators allows for the rapid acquisition of large amounts of infrared images of insulators in service, which can be used to analyse their operational status. However, efficiently and accurately analysing these images remains a challenge.

High Voltage, EarlyView.ABSTRACT This study presents a comparative analysis of six machine learning algorithms for automated hydrophobicity classification in composite insulators using contour‐based image features. A robust image‐processing pipeline was developed to extract statistical features from water droplet patterns on insulator surfaces, enabling objective ...
