Abstract
To detect the partial discharge (PD) faults in three-phase cross-linked polyethylene (XLPE) cable joints, this paper designs a parallel sensing detection system based on fiber Bragg gratings (FBG). By measuring the changes in the reflected power of FBGs in each branch and combining with a Back Propagation (BP) neural network algorithm, the demodulation of temperature and strain during PD is achieved. To verify the feasibility of this system, vibration signals and temperature changes are respectively applied to each FBG, and simulation experiments are carried out. The experimental results show that this system can accurately detect the temperature changes, the frequencies of vibration signals, and the strains in each branch, verifying its feasibility for detecting cable joint faults. In addition, by adjusting the sampling frequency of the photodetector, higher-frequency vibration signals can be measured.

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
