Abstract

fetched live from OpenAlex

This paper describes the design of a distance relay that uses adaptive data window filters to provide high speed tripping. The relay uses a fault detector to detect the inception of a fault. Starting from the fault detection, the data window size is progressively increased as new fault samples become available until the window size becomes one cycle of the fundamental frequency. At each instant, a suitable filter is used for estimating voltage and current phasors. This procedure improves the transient response of the relay and allows faster convergence of the impedance estimates and, therefore, reduces the trip time. The proposed relay was tested by using fault simulations on a sample power system. Results indicate that the proposed relay design reduces the trip times. Some results are included.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
