Abstract
as formas de realização da divulgação referem-se à detecção de falhas entre espiras em um ou mais enrolamentos de vários objetos. em uma implementação, um detector de falhas usa um algoritmo de proteção diferencial para detectar uma falha entre espiras em um enrolamento de um reator de desvio trifásico. várias medições de tensão e corrente realizadas no reator de desvio trifásico são usadas para calcular um valor de diferença entre um parâmetro baseado em tensão e um parâmetro baseado em corrente. o parâmetro baseado em tensão é indicativo de um desequilíbrio de tensão negativo normalizado e o parâmetro baseado em corrente é indicativo de um desequilíbrio de corrente negativo normalizado. uma falha de enrolamento entre espiras é declarada quando o valor da diferença não é igual a zero.
