Abstract

"sistema e método para detectar falhas de enrolamento-para-aterramento, e, dispositivo eletrônico inteligente" um sistema para detectar falhas de enrolamento-para-aterramento é revelado, o qual inclui uma fonte de injeção de sinal em comunicação elétrica com um enrolamento de um gerador de energia elétrica via um transformador de injeção. o enrolamento pode se acoplado ao aterramento via um trajeto enrolamento-para-aterramento e a fonte de geração de sinal pode gerar um sinal de injeção capaz de ser injetado no enrolamento usando o transformador de injeção. o sistema revelado pode ainda incluir um módulo de proteção em comunicação com a fonte de injeção de sinal e o gerador de energia elétrica configurado para receber o sinal de injeção e um sinal relativo à corrente através do trajeto enrolamento-para-aterramento, e para determinar a ocorrência de uma condição de falha de enrolamento-para-aterramento com base, pelo menos parcialmente, no sinal de injeção e no sinal relativo à corrente através do trajeto enrolamento-para-aterramento.
