An energy meter receives the first respective signal, the second respective signal, and the third respective signal, and determines a power level.

Abstract: A sensor for detecting voltage of a power cable includes a housing configured to be coupled around at least a portion of the power cable. A first conductive element supported by the housing is configured to be electrically coupled to the power cable when the housing is coupled around at least a portion of the power cable. A first capacitive element supported by the housing is electrically interconnected with the first conductive element. A second capacitive element supported by the housing is electrically interconnected with the first conductive element. A processor determines a cable capacitance of the power cable based upon alternatively sensing an electrical characteristic (i) the first capacitive element and the second capacitive element and (ii) the first capacitive element without the second capacitive element. The sensor determines the voltage of the power cable based upon the determined cable capacitance.
