Scope

Scope: This document specifies the operational requirements, implementation, data processing, and analysis for drone-based multispectral inspections of the contamination status of overhead transmission line insulators. This document is applicable to the multispectral drone inspections of composite, ceramic, and glass insulators on overhead transmission lines with voltages of 110 (66) kV and above, including both AC and DC transmission lines. Key technical content: Insulators are important mechanical support and electrical insulation devices in transmission lines. Due to their long-term exposure to outdoor environments, the surfaces of insulators come into contact with various contaminants in the air, leading to surface contamination. Under certain conditions, this contamination may cause flashover, which threatens the safe operation of transmission lines. Spectral detection technology uses multiple extremely narrow electromagnetic waves in the visible, near-infrared, infrared, and thermal infrared wavelength ranges to periodically acquire continuous spectral images of objects, integrating imaging and spectral technologies. This technology accurately describes the reflectance spectrum of objects and improves their classification and identification capabilities. Combined with drones, it enables non-contact and safe acquisition of insulator spectral images. Based on spectral contamination assessment models, the contamination status of insulators can be quickly determined. With the increasing demand for insulator contamination detection, there is an urgent need to improve current industry standards and enhance industry norms. This document is formulated in accordance with relevant national laws, regulations, and industry-related standards and experiences. It serves as the foundation for the promotion and application of multispectral insulator contamination detection technology, scientifically and rationally standardizing the components, general requirements, and data an
