Abstract

fetched live from OpenAlex

Investigations carried out on ferroresonant oscillations in a transformer-terminated line due to an energised parallel line on the same right-of-way are reported. A nonlinear approach is used for analysis. The magnetic saturation characteristic of the individual phases of the three-phase transformer is represented and modelled by a polynomial. A topological technique is used to formulate the state space model to eliminate redundancy. Time domain simulations have been carried out using fourth-order Runge-Kutta method after corroboration with Microtran. The bifurcation diagram of the steady-state solutions is used to unearth the possible modes of ferroresonant oscillations and multiple solutions. The results reveal that with high saturation levels, chaotic ferroresonant oscillations are a distinct possibility due to the capacitive coupling between the parallel lines. Furthermore, the route to chaos is through a sequence of quasiperiodic oscillations. The sensitivities of the solutions with respect to the length of the de-energised line and the proximity between the parallel lines are analysed and discussed.

Full frame distilled prediction

Teacher imitation

Not 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.
