基于漏电流瞬态特性的变频电机对地绝缘多样化评估

Real-time assessment of ground-wall (GW) insulation condition is critical for the reliable operation of inverter-fed motors (IFMs) and many online monitoring methods have been proposed. However, the existing methods can only detect the overall insulation degradation condition, the refined assessment of degradation position is rarely reported. In this article, a diversified assessment method is pro...
