The HQ LineROVer: contributing to innovation in transmission line maintenance
Bibliographic record
Abstract
Innovations in transmission line maintenance have had a significant impact at many levels, including equipment reliability, continuity of service, inspection accuracy and efficiency, cost-effectiveness in maintenance practices, follow-up and safety. New live-line tools and methods will help utilities maintain the reliability of their aging transmission line installations in a challenging market. The HQ LineROVer was first presented as an overhead ground wire de-icing application in 2000 (ESMO conference). The prototype has since evolved into a third generation remotely operated vehicle (ROV). Many maintenance applications are now being targeted: visual and infrared inspection, evaluation of compression splice conditions (resistance measurements), replacement of conductors and ground wires (live), cleaning and de-icing of conductors. Live-line inspections have been realized on Hydro-Quebec's transmission network. Many other utilities throughout the world plan to use the ROV for their specific needs. The economic and strategic impacts of this new tool have been proven. Ongoing work on the HQ LineROVer and other ROVs will lead to the development of new live-line methods for transmission line maintenance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
