Abstract
Electrical machines are used widely in the petrochemical industry. Most of the machines are operated in Class I hazardous locations and hence appropriate precautions must be taken to protect the machine to ensure that the explosive atmosphere cannot be ignited. There are four types of protection applicable to large machines. They are type p (purged and pressurized), type e (increased safety), type d (flameproof) and type N. Type p, type e and type d protections are permitted in Zone 1 or Zone 2. In 1996 and 1999, two machines were designed and tested to meet IEC 60079-0 and 60079-7 standards regarding Exe II B 200/spl deg/C (T3) requirement. The machines are installed in Zone 2 locations. The paper presents the electrical and mechanical design consideration of the increased safety induction machine. Finally, the paper describes the test procedure and summarizes the results from the series of tests performed on these two machines.

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 it
