IEC TR 63439-1-2:2026 ED1

Robotics for electricity generation, transmission and distribution systems - Part 1-2: State-of-the art and standardization roadmap for electric power system robots

Scope

IEC TR 63439-1-2:2026 specifies a comprehensive study of the robotic technologies in power systems, including generation, transmission, and distribution. The primary objectives are:
a) System overview and classification
Analyze current robotic applications across all power system segments (generation, transmission, and distribution), developing a comprehensive classification framework that categorizes robots by operational scenarios (substations, power lines), functional roles (inspection, repair), and environmental conditions (high-voltage zones, confined spaces).
b) Core technology assessment
Evaluate fundamental robotic technologies encompassing mobility platforms (ground robots, drones, remotely operated vehicles (ROVs), navigation systems (GPS, LiDAR, vision-based), and communication networks (wired/wireless/hybrid); assess functional capabilities through multi-sensor inspection (visual, thermal, ultrasonic) and maintenance operations (live-line work, cleaning, debris removal), and examine integration aspects with power grid management systems including data protocols and cybersecurity requirements.
c) Testing and validation framework
Establish performance benchmarks for core robotic functions including autonomous navigation, inspection accuracy, and operational efficiency, while developing reliability testing methods that incorporate failure mode analysis (FMEA/FMECA) and environmental stress testing under extreme conditions.
d) Standardization roadmap
Conduct a gap analysis of current power robotics standards (including IEC/TC129) to identify deficiencies, while systematically mapping stakeholder requirements to prioritize standardization needs across hardware, software interfaces, and safety protocols; develop the roadmap with clear timelines for creating new standards, facilitating adoption, and ensuring compliance verification across the industry.
