Abstract

Coupling apparatus is provided for assembly with separable insulated connector components on power cables for power distribution systems. The coupling apparatus provides either direct or indirect coupling, e.g. to provide interconnection to the connector components or to provide a sensing point. In one illustrative embodiment, the coupling apparatus is installed in place of a conventional double-ended plug that is required to piggyback T-body elbows, i.e.
where multiple elbows are to be connected. In one specific arrangement, the coupling apparatus includes a desired connector interface. In another specific arrangement, a sensed voltage output is provided using components such as capacitive coupling components, capacitors, resistors or transformers. In another embodiment, the coupling apparatus is used in place of a conventional insulating plug that is used to attach a T-body elbow to a bushing, e.g. on switchgear assemblies or the like. In a specific arrangement, the coupling apparatus is a voltage sensor and provides a sensed voltage output derived from a capacitive coupling arrangement utilizing a capacitive divider. In a preferred form, the voltage sensor also encapsulates circuitry to provide a low impedance output signal that is directly proportional to the sensed voltage.
