A fault indicator for use in conjunction with a load-break elbow connector includes a resilient mounting collar which wraps around the body of the fault indicator at a location overlying the arc-suppressing non-conductive margin between the electrically conductive sheath and the connecting end of the connector. An electrically conductive layer on the inside surface of the collar capacitively couples the circuitry of the fault indicator to the conductor within the connector to provide operating power to the fault indicator. A ground connection is provided by a second conductive layer on the collar which contacts the grounded connector sheath, or by a spring contact which extends from the fault indicator to the sheath. A voltage indicator is also disclosed using the same collar and capacitive coupling to the monitored conductor.

Indicateur d'anomalie pour connecteur interrupteur de charge coudé, comprenant une bague élastique qui entoure le corps de l'indicateur à l'endroit qui recouvre la bordure non conductrice éliminatrice d'arc entre la gaine conductrice et l'extrémité de raccordement du connecteur. Une couche conductrice sur la surface interne de la bague forme un couplage capacitif entre les circuits de l'indicateur d'anomalie et le conducteur situé dans le connecteur, de manière à alimenter l'indicateur d'anomalie. Ce dernier est mis à la terre au moyen d'une seconde couche conductrice sur la bague, qui est en contact avec la gaine du connecteur mise à la terre, ou d'un contact à ressort reliant l'indicateur d'anomalie à la gaine. La présente invention fait également état d'un détecteur de tension se servant du même type de bague et d'un couplage capacitif avec le conducteur contrôlé.
