Abstract
A power distribution system is described for supplying power to electronic assemblies, in particular for use in the field of deep ocean oil production. The electrical power is supplied from a voltage source via a supply cable to theprimary winding of a distribution transformer. A number of secondary windings, preferably four, are disposed in addition to the primary winding on the core of the distribution transformer. The windings on the common core are subdivided into a number n of winding packs corresponding to the number n of secondary windings, and with each winding pack containing an n-th part of the primary winding and one of the secondary windings. Electronic assemblies are each connected via a connecting cable to one of the secondary windings.
