Abstract
Defects in high voltage transmission line components such as cracked insulators, broken wires rope, and corroded power line joints, are very common due to continuous exposure of these components to harsh environmental conditions. Consequently, they pose a great threat to humans and the environment. This paper presents a real-time aerial power line inspection system that aims to detect power line components such as insulators (polymer and porcelain), splitters, damper-weights, power lines, and then analyze these transmission line components for potential defects. The proposed system employs a deep learning-based framework using Jetson TX2 embedded platform for the real-time detection and localization of these components from a live video captured by remote-controlled drone. The detected components are then analyzed using novel defect detection algorithms, presented in this paper. Results show that the proposed detection and localization system is robust against highly cluttered environment, while the proposed defect analyzer outperforms similar researches in terms of defect detection precision and recall. With the help of the proposed system automatic defect analyzing system, manual inspection time can be reduced.
Highlights
The basic components of the electricity transmission system or grids include transmission power line, transmission towers, insulators, balisor beacon, sag adjusters, etc., play an important role in the safe transmission of electricity between a grid station and a local distribution station [1]
Unlike earlier studies that use handcraft features, this study explores the robustness of the Convolutional Neural Network-Based (CNN)
We present the experimental results of the transmission line components
Summary
The basic components of the electricity transmission system or grids include transmission power line, transmission towers, insulators, balisor beacon, sag adjusters, etc., play an important role in the safe transmission of electricity between a grid station and a local distribution station [1]. According to the Occupational Safety and Health Organization (OSHA), 576 fatalities and accidents related to electric repairmen were reported between May 2016 and April 2017, only in North America [4]. To avoid such incidents, electrical companies are incorporating patrolling helicopters for inspection and repairing operations of these electrical components in remote areas and ground vehicles in urban areas to take high-resolution pictures or videos of the power lines, transmission towers, and insulators, and analyze them for their potential defects [5]
