Abstract: A power distribution arrangement, especially in an aircraft, includes plural power sources, a power line having plural power supply strands connected to the power sources, plural power consumer groups each including plural power consuming devices, and branch lines respectively connecting the power line with the power consumer groups. A respective allocation unit selectively interconnects the power consuming devices of each group with selected individual branch line strands of the branch lines. A status unit acquires information regarding the respective operating status of the power sources and the power line strands, and conveys corresponding information regarding a power failure on any power line strand to a central power control unit, which correspondingly transmits control commands over a control bus to the respective allocation units.
