Abstract
MÉTODO E APARELHO PARA MEDIR CORRENTES DE ROLAMENTO EM UMA MÁQUINA ELÉTRICA. A presente invenção refere-se a um método e aparelho para medir as correntes de rolamento em uma máquina elétrica (2). Os sinais de frequência de rádio que são gerados por descargas elétricas são detectados por uma antena (16) próximo do rolamento (14). Um sinal de sincronização é combinado com a origem da corrente de rolamento e o sinal disparado pelo sinal de sincronização é medido.
