Abstract

fetched live from OpenAlex

This investigation was prompted by a cable fault explosion inside a cable duct which housed a BC Hydro 15 kV underground standby feeder cable. The incident occurred in September 1998 at a housing complex in Vancouver, BC, Canada. Damage to the building vault was extensive and could very easily have resulted in severe injury or a fatality had anyone been in the immediate area of the vault. A failure analysis investigation revealed that the cause of the explosion was an accumulation of combustible gases which were decomposition products of the polymeric cable components which were liberated from the cable by a long duration high impedance fault. Several unusual circumstances had to occur concurrently to allow the explosive condition to develop. The events that led to the explosion are discussed in terms of the failure mechanism of the cable and the effects of reclosure arcing.

Teacher imitation

Not 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.
