Abstract
A method of estimating a line voltage is provided that includes configuring a capacitive probe to a power line, injecting a perturbation voltage onto the capacitive probe, where the perturbation voltage has a different frequency than a frequency of the line voltage, measuring, using a capacitive sensor, a retrieved perturbation voltage, where the retrieved perturbation voltage is dependent on a capacitance between the capacitive probe and a ground capacitance, using an appropriately programmed computer to track real time changes in the capacitance of the capacitive probe, and estimating a line voltage.
