Abstract
Embodiments of the invention provide for a circuit that detects a contact between a high-voltage power source and an electrically-conductive non-grounded device. A probe may conduct an electric potential from the electrically-conductive device to the circuit. A first leg of the circuit may shift the phase of the electric potential of the first leg relative to a phase of the electric potential of a second leg of the circuit. A voltage indicative of the phase difference of the electric potential between the first leg and the second leg may be measured. The detected voltage may be indicative of the contact between the high-voltage power source and the electrically-conductive device.
