Abstract
Systems, methods, and an apparatus for current monitoring are disclosed. A current monitor comprises a high-voltage side configured to obtain a signal indicative of current through a conductor and apply different levels of gain to different frequency bands of the signal to produce an adjusted signal. A low-voltage side of the current monitor is electrically isolated from the high-voltage side and is configured to split the adjusted signal to produce a plurality of output signals that are each indicative of a level of current at one of the different frequency bands. An isolation amplifier is configured to communicate the adjusted signal from the high-voltage side to the low-voltage side while electrically isolating the high-voltage side from the low-voltage side.
