Abstract
Disclosed are power distribution systems and methods in which a power distribution unit (PDU) is provided with an overcurrent protection device and per-outlet current sensing at each of the multiple electrical outlets of the PDU. The described embodiments enable the identification of the electronic device connected to a specific outlet or electronic device that may have caused the overcurrent protection device to trip. The methods of outlet identification in a PDU having multiple electrical outlets includes detecting whether either a peak current or a half-cycle root mean square (RMS) current at each outlet has exceeded a selected threshold prior to the occurrence of the trip event associated with the overcurrent protection device.
