A method and apparatus for detecting motor contamination utilizes zero- sequence currents in a sensing coil to detect contamination. The detector includes a current transformer comprised of a magnetic core and a sensing coil wound about the core. A processor processes a sub-trip level current from the sensing coil to detect contamination. Three contamination detection methods, which may be used separately or in desired combination, are based on current trends, current leakage, and current clustering. An alarm is triggered when predetermined alarm criteria have been met.

L'invention concerne un procédé et un appareil, permettant de détecter la contamination d'un moteur, qui utilise des courants homopolaires dans une bobine de détection, afin de détecter une contamination. Le détecteur comprend un transformateur de courant composé d'un noyau magnétique et une bobine de détection enroulée autour du noyau. Un processeur traite une intensité de courant inférieure au niveau de déclenchement, à partir de la bobine de détection, afin de détecter une contamination. Trois procédés de détection de contamination, pouvant être utilisés séparément ou en combinaison, sont établis sur des tendances de courant, des fuites de courant et des regroupements de courant. Une alarme se déclenche lorsqu'on rencontre un critère d'alarme prédéterminé.
