Abstract
A device for detecting proximity to an active alternating current (AC) voltage source is provided. The device includes a housing, at least one antenna configured to generate a signal in response to exposure to electromagnetic radiation, signal processing circuitry configured to process the signal generated by the at least one antenna, a microprocessor configured to determine, from the processed signal, whether the alert device is proximate to the active AC voltage source, a communication device configured to generate a signal in response to a determination that the alert device is proximate the active AC voltage source, and an interference reduction device configured to discharge an accumulated charge on the alert device to reduce electromagnetic interference from sources other than the active AC voltage source.
