Voltage sensor systems and methods

摘要

An exemplary embodiment of the present invention provides a floating voltage sensor system comprising a metallic enclosure, a conductive sensor plate, a signal conditioning circuit, and a microcontroller unit. The metallic enclosure can be configured for electrical communication with an asset carrying a voltage. The conductive sensor plate can be positioned adjacent to a surface of the metallic enclosure, such that the conductive plate and the surface of the metallic enclosure are not in contact with each other. The signal conditioning circuit can comprise a first connection point and a second connection point. The first connection point can be in electrical communication with the conductive sensor plate. The second connection point can be in electrical communication with the metallic enclosure. The microcontroller unit can be configured to receive an output of the signal conditioning circuit and measure the voltage of the asset.
