Digital power network method and apparatus

A method for routing digital electric power among power control elements, the method comprising:

• routing digital electric power with at least one digital electric power routing device among a plurality of power control elements, each power control element having at least two sets of power terminals, and the digital electric power routing device including (a) at least one DC power bus;
• (b) at least two of the power control elements, wherein at least one power terminal of each power control element is connected to the DC power bus;
• and (c) at least one network controller;
• transmitting electrical power in packet energy transfer format with at least one of the sets of power terminals;
• executing control functions using the network controller within the power control elements to determine routing of electrical power and to route electrical power from at least one power control element to at least one other power control element within a digital power network;
• electrically isolating the power terminals;
• and
• analyzing voltage characteristics at the power terminals before and after the power terminals are electrically isolated to evaluate whether a fault condition exists.
