Abstract
Effects of various design and operating parameters on the hot-spot temperature are analyzed in disk-type forced oil-cooled transformer windings. The results indicate that a two-dimensional thermal analysis in the disks is necessary to determine the temperature and location of the hottest spot, and that the cooling oil-flow arrangement has a significant influence on the cooling of disk windings. The maximum disk temperature for each pass is proportional to the oil entrance temperature and, therefore, the heat transfer in the radiator should be improved as much as possible. A larger total oil-flow rate through the pass can increase the cooling capacity and, hence, improve the cooling of the disks, but increases the pressure loss. Although a uniform distribution of cooling oil flow among the various horizontal cooling ducts within a pass is beneficial to decrease the hottest spot temperature, the best cooling results can be obtained when the cooling flow distribution matches the distribution of heat generation in each disk of the pass.

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 it
