Abstract
Disclosed is a voltage sensing apparatus comprising a signal generator coupled to a first conducting layer and a conductive element having a first voltage, the signal generator configured to superimpose a second voltage to the first voltage. The voltage sensing apparatus also comprises a meter disposed between the first conducting layer and a second conducting layer or between the signal generator and the second conducting layer. An output parameter of the meter is a function of one or more of the group consisting of: the first voltage and the second voltage. The output parameter and the second voltage can be used to adjust a determination of the first voltage.
Claims21
A voltage sensing apparatus, comprising:
- a signal generator coupled to a first conducting layer and a conductive element, the conductive element comprising a power line, the conductive element having a first voltage,
- wherein the first conducting layer is separated from the conductive element by an insulating layer,
- wherein the signal generator is adapted to superimpose a second voltage to the first voltage;
