Title (EN) MONITORING HEALTH OF ELECTRICAL EQUIPMENT
(FR) SURVEILLANCE DE LA SANTÉ D'UN ÉQUIPEMENT ÉLECTRIQUE
Abstract:
(EN) Techniques for monitoring the health of a device comprising a motor or generator are described. An apparatus to monitor the health of the device includes a plurality of sensors to detect root-mean-square (RMS) current values for a plurality of stator windings of the device. The apparatus also includes a processor to receive the RMS current values from the plurality of sensors and compute a fault indicator based on the RMS current values. The fault indicator represents a level of current imbalance between the plurality of stator windings due to winding faults.
(FR) L'invention concerne des techniques de surveillance de la santé d'un dispositif comprenant un moteur ou un générateur. Un appareil servant à surveiller la santé du dispositif comprend une pluralité de capteurs destinés à détecter des valeurs de courant moyennes quadratiques (RMS) pour une pluralité d'enroulements statoriques du dispositif. L'appareil comprend également un processeur destiné à recevoir les valeurs de courant RMS de la pluralité de capteurs et calculer un indicateur de défaut en se basant sur les valeurs de courant RMS. L'indicateur de défaut représente un niveau de déséquilibre de courant entre la pluralité d'enroulements statoriques en raison de défauts d'enroulement.
