Abstract

"MéTODO E SISTEMA PARA AVALIAçãO DA OPERAçãO DE UM ALTERNADOR". Método e sistema para avaliar a operação de um alternador, com base em um componente de freq³ência no sinal de saída do alternador. O método compreende a detecção de um componente de freq³ência do sinal de saída do alternador, comparando o componente de freq³ência do sinal de saída do alternador com um limite de freq³ência e avaliando a operação do alternador com base no resultado da comparação. Caso o componente de freq³ência do sinal de saída do alternador seja menor que o limite de freq³ência, o alternador é considerado defeituoso. O componente de freq³ência pode ser obtido através de comparação do sinal de saída do alternador com um limite adaptativo. O limite adaptativo é gerado com base no nível de sinal de pico e no nível de sinal inferior do sinal de saída do alternador, tal como, a média do nível do sinal de pico e do nível de sinal inferior.
