Abstract
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.
