Article Synopsis
- High-voltage power line insulators are essential for safe electricity transmission, but real-world image limitations hinder the development of effective inspection algorithms, especially for dirty insulators.
- A new synthetic image database has been created using CAD models and game engines to simulate various insulator types and environmental conditions, providing a diverse dataset for research.
- This database includes an Image Segmentation Set with over 47,000 images by material and landscape, and an Image Classification Set with about 14,000 images showing different contaminants, aimed at improving machine learning for insulator inspection.
The inspection and maintenance of transmission systems are necessary for their proper functioning. In this way, among the line's critical points are the insulator chains, which are responsible for providing insulation between conductors and structures. The accumulation of pollutants on the insulator surface can cause failures in the power system, leading to power supply interruptions.
