ANÁLISE DAS TENSÕES INDUZIDAS EM TORRES DE TRANSMISSÃO USANDO MÉTODO DOS MOMENTOS
Bibliographic record
Abstract
O backflashover e uma das principais causas de interrupcoes nos sistemas de energia devido as tensoes induzidas provocadas por descargas atmosfericas. Neste contexto, a impedância de aterramento e a impedância de surto de torre sao determinantes nas tensoes induzidas provocadas por esse fenomeno. Esses parâmetros sao estimados por varios modelos e metodos numericos, nos quais o eletrodo de aterramento e representado por modelos a parâmetros distribuidos ou concentrados e a impedância de surto da torre e calculada por modelos geometricos. Metodos numericos sao aplicados nas equacoes de Maxwell aplicadas nos eletrodos e em torres de transmissao altas. Neste artigo, o Metodo dos Momentos e utilizado para o calculo da impedância de eletrodos de aterramento no dominio da frequencia e os resultados sao comparados com o modelo classico da linha de transmissao. As admitâncias de duas torres de transmissao sao calculadas pelo mesmo metodo. Em seguida, um circuito eletrico e aproximado para cada curva usando Vector Fitting. Com esses circuitos, as tensoes induzidas sao calculadas no PSCAD®, a influencia de alguns parâmetros e observada e os backflashovers podem ser estimados com mais precisao.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
