Abstract
A transformer is the most widely used equipment in power systems to transfer energy from one circuit to another. For real-time electromagnetic transient simulation, this paper presents a digital hardware emulation of the power transformer on a field programmable gate array. The linear model of the transformer is based on the admittance matrix approach. Detailed real-time modeling of the transient nonlinearities, including hysteresis phenomena, is carried out based on the Preisach theory. The nonlinear solution in real time is undertaken using a full Newton iteration. All the hardware modules for the transformer emulation were developed in VHDL. The model is fully parallelized and pipelined to achieve the lowest latency and the smallest hardware resource consumption. Real-time results on the oscilloscope are compared with off-line results from the ATP software.

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
