Abstract
This study presents the concept, implementation and test results of a fault direction identification method that applies to identify faulty segments in transmission systems. This method relies on the wavelet analysis of the transient currents. Exchange of fault direction information among intelligent electronics devices located at different locations of network permits identification and isolation of the faulty network segment. A prototype of the fault direction identification unit was implemented using a floating point digital signal processor platform. The performance of the prototype was tested with current signals generated using a real-time waveform playback instrument. The transient waveforms were obtained from an extra high-voltage transmission system simulated in electromagnetic transient-type simulation program. Investigations were carried out under different scenarios such as current transformer saturations, measurement noise etc.

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
