Design and Testing of 500kV Double Circuit Monopoles for the Heartland Transmission Project in Edmonton, Alberta
Bibliographic record
Abstract
The Heartland Transmission Project is a recently built 500kV double circuit transmission line near Edmonton, Alberta, Canada. The scope of the project was to connect the existing Ellerslie Substation, located within Edmonton, to the new Heartland Substation, located approximately 65 kilometers northeast of Edmonton in the Heartland Industrial Area, near Fort Saskatchewan, Alberta. Approximately half of the line was built within a designated Transportation and Utility Corridor (TUC) with a section passing between the communities of Edmonton and Sherwood Park. The Alberta Utility Commission (AUC) declared that a 10 km section of the line passing between the communities of Edmonton and Sherwood Park were to be built using tubular steel structures rather than the traditional lattice steel towers. The process of developing a family of tubular monopoles consisting of tangent, light, and medium angle suspension towers and site-specific dead-end towers is outlined. The design, from a conceptual stage through to the project’s completion is discussed. Topics will cover the development of pole design requirement drawings, structure design, manufacturing, full scale testing, and foundation design.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
