Patent ID: 8885306

Claim:
An AC or DC power management and distribution system having a fault detection and isolation assembly comprising: at least one source block having a power distribution line, wherein the power distribution line includes a distribution switch; at least one power source supply line for distributing power to the at least one source block, wherein the at least one power source supply line comprises a plurality of source switches; at least one load block in operable communication with the power distribution line and having a plurality of load block power input lines and output lines, wherein each of the plurality of load block power output lines includes a load switch; a plurality of loads each carried power by at least one of the plurality of load block power output lines; and a protection logic unit comprising at least one algorithm for comparing a current differential to a current differential threshold at a plurality of locations, wherein the protection logic unit selectively determines which of the source switches, distribution switches and load switches of the are opened based on at least one comparison, wherein the plurality of locations comprises the source block input line, between the source switch and the distribution switch, between the distribution switch and the load block input line, proximate one of the load switches, and between the load switches and the loads.
