Within a power generating arrangement 1 it is typically necessary to provide a coupling with an electrical power distribution cable 5. Previously this was sometimes achieved through use of brush gear and slip rings but such arrangements are subject to regular replacement for wear, maintenance and also there is a requirement to control humidity about the brush gear coupling. Alternatively, a system allowing an amount of rotation, limited by cable wind up was used. By providing a transformer in wh...

An abnormality of a generator provided with a plurality of power supply units is easily detected. Each of the power supply units includes each of output windings L1 to L4, which are wound independently of each other around the single iron core, and each of rectifier circuits 2 to 5. The power supply units produce an integrated output power. Control means 33 to 35 control the rectifier circuits such that an output voltage agrees with a target voltage Vref. In a case where an added up power W beco...
