Title
(EN) SYSTEMS AND METHODS TO MITIGATE ELECTRICAL VOLTAGE ON A ROTATING SHAFT IN OIL
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT D'ATTÉNUER UNE TENSION ÉLECTRIQUE SUR UN ARBRE ROTATIF DANS DE L'HUILE
Abstract
(EN) Systems and methods to mitigate electrical voltage on a rotating shaft in an oil rich environment exposed to a viscous fluid or immersed in oil are disclosed. An example grounding brush assembly includes a plurality of conductive filaments configured to extend through the viscous medium surrounding the rotating shaft to be in electrical contact with the rotating shaft when the brush assembly is disposed proximate the shaft.
(FR) Des systèmes et des procédés permettant d'atténuer une tension électrique sur un arbre rotatif dans un environnement riche en huile exposé à un fluide visqueux ou immergé dans de l'huile sont divulgués. Un exemple d'ensemble balai de mise à la terre comprend une pluralité de filaments conducteurs conçus pour s'étendre à travers le milieu visqueux entourant l'arbre rotatif pour être en contact électrique avec l'arbre rotatif lorsque l'ensemble balai est disposé à proximité de l'arbre.
