Standards Development
This standard specifies the general requirements, test methods, and acceptance criteria for robotic inspection systems used in overhead transmission lines. It defines the system composition, classification, performance requirements, testing procedures, inspection rules, marking, packaging, transportation, and storage. The standard applies to inspection robots designed to operate along the ground wire of overhead transmission lines rated 110kV (66kV) and above. It does not cover ground-based inspection robots, unmanned aerial vehicle (UAV) inspection systems, or other non-contact inspection technologies.
As the scale of global power grids expands and the pace of intelligent development accelerates, inspection methods for overhead transmission lines are undergoing a significant transformation. Traditional manual inspections are increasingly inadequate due to harsh working environments, low efficiency, and discontinuous data collection, making them unable to meet the modern power grid’s demands for efficient, safe, and precise inspections. Although drones and helicopters have enhanced inspection capabilities, their operations are constrained by weather conditions, electromagnetic interference, limited endurance, and high costs, preventing them from delivering continuous and stable inspection coverage. In this context, robotic inspection systems for overhead transmission lines have emerged as a critical technology for intelligent grid operations. With capabilities such as all-weather autonomous operation, high-precision detection, remote control, and intelligent data analysis, these systems are becoming indispensable tools for real-time monitoring and precise management of transmission line conditions.
However, there is currently no unified international standard for robotic inspection systems applied to transmission lines. Differences in performance specifications, communication protocols, data formats, and environmental adaptability among manufacturers hinder interoperability and widespread adoption. Moreover, the lack of standardized testing and evaluation methods makes it difficult to ensure the reliability, safety, and cost-effectiveness of these systems.
This standard aims to establish general requirements, test methods, and acceptance criteria for robotic inspection systems used on overhead transmission lines, ensuring interoperability and data compatibility across different equipment. By defining standardized performance and testing criteria, this standard enhances the stability, reliability, and practical applicability of robotic inspection technologies. Its implementation will promote the global standardization of such systems in the power industry, support the development of intelligent grids, improve operational efficiency and reliability, reduce inspection costs and safety risks, and foster technological innovation and market growth. Ultimately, it will lay a solid foundation for the digital and intelligent transformation of future power grid operations.
