Abstract
To provide protection for power supplies in which a plurality of paralleled identical DC power cables are provided between a source and a load, one aspect of the present invention provides a method for detecting conditions in parallel DC power cables. The method includes supplying current from a power supply to each of a plurality of DC power cables, determining an average current per cable flowing in the plurality of parallel DC power cables, comparing currents in each of the DC power cables with the determined average current, and signaling the existence of a condition in response to the comparison.
