Abstract
resumo patente de invenção: "método e dispositivo para detecção de uma deterioração no estado de um isolamento na operação de uma máquina elétrica". a presente invenção refere-se a um método e a um dispositivo (1) para a detecção online de uma deterioração no estado de um isolamento em uma máquina elétrica (2). uma tensão em passos é aplicada ao(s) enrolamento(s) (3) da máquina (2) com o auxílio de um conversor (41), e a corrente (i) induzida desta forma, e/ou o tempo derivado (di/dt) deste, é adquirido como um sinal de medição com o auxílio de pelo menos um sensor (6, 7, 8) e é então sobreamostrado com uma frequência mais alta do que as frequências características para o ajuste. o sinal obtido pela dita superamostragem é então avaliado com relação aos parâmetros do processo de ajuste como a superação (ah) e/ou frequência natural (i/?t) e/ou um amortecimento constante, para detectar qualquer deterioração no isolamento.
