Performance of RTV silicone rubber insulator coatings
Bibliographic record
Abstract
The results of the performance of room-temperature vulcanizing (RTV) silicone rubber insulator coatings in a salt-fog chamber are presented. The coatings were evaluated at 900- mu S/cm conductivity for the water forming the salt-fog. The loss of hydrophobicity was studied from monitoring the leakage current on the coatings. The effect of scale formed during dry band arcing was evaluated with respect to the performance of RTV coatings. The development of leakage current on the RTV coatings without scale is associated with a temporary loss of surface hydrophobicity. However, with scale deposited during dry band arcing the leakage current development is not only dependent on the temporary loss of hydrophobicity, but also strongly dependent on the amount of scale. The flashover voltage of the RTV coatings was determined subsequent to varying the time of the application of the electric stress in the salt fog. The performance of RTV coatings was studied as a function of the alumina trihydrate (ATH) filler level. Leakage current and contact angle measurements were used as indicators of the effectiveness of the RTV coatings. RTV coatings enable insulation systems to attain increased flashover performance by about 30% over uncoated insulators.>

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.
