Abstract
It is critically important to understand steady-state and dynamic performance of phasor measurement units (PMUs) to ensure reliable and secure operation of the synchrophasor based wide area monitoring, control, and protection systems. The recently published IEEE Standard C37.118.1 provides necessary guidelines to characterize both steady-state and dynamic performance of a PMU. This paper presents a performance evaluation methodology according to the IEEE Standard C37.118.1 and discusses the practical issues in the test environment. Results of the steady-state and dynamic responses tests on an actual PMU are also presented. The PMU performance evaluation approach of this paper is simple, repeatable, and can be performed at any facility with commonly available standard signal playback equipment. The method is based upon using test signals that are mathematically generated from a signal model and play backed into the PMU with precise global position system (GPS) synchronization.

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
