Patent ID: 8680845

Claim:
A sensor for sensing an electric potential on a wire of a power distribution system and a current passing through the wire, the sensor comprising: a housing for detachably coupling the sensor to the wire; a current sensing device integrated in the housing for providing a first output indicative of the current passing through the wire, wherein the current sensing device comprises at least two ferrite cylinder portions disposed within the housing, wherein when the housing is coupled to the wire, the wire passes through a central void defined by the ferrite cylinder portions extending through a central axis thereof, and wherein a gap is defined along a circumference of a cylinder formed by the ferrite cylinder portions, and wherein the current sensing device further comprises a semiconductor magnetic field sensor disposed within the gap, wherein the second output is a voltage output of the semiconductor magnetic field sensor; and a voltage sensing device integrated in the housing for providing a second output indicative of the electric potential on the wire, wherein the voltage sensing device and the current sensing device do not make electrical contact with the wire.
