Abstract
Disclosed are power distribution systems and methods in which a power distribution unit (PDU) includes a residual current monitor (RCM) to detect the presence of downstream leakage current in the PDU. The RCM can include a current sensor with a core that has power conductors passing through the core and drive windings about the core. Drive circuitry of the RCM produce alternating drive signals through the drive windings to drive the core into and out of positive and negative saturation. Sensing circuitry of the RCM produce a response signal that is filtered by a high-order current signal filter to isolate characteristics of the downstream leakage current.
