Abstract

The invention relates to an electrical DC power supply system for underwater and above water vessels and for offshore installations with at least one DC source (12 13) arranged in a respective source phase and at least one DC drive motor (2) arranged in a respective motor phase. Furthermore the invention relates to a method for influencing a direct current flowing in a DC power supply system. In order to ensure improved protection in the event of a short circuit in an electrical DC power supply system it is proposed to provide in each case at least one current measuring device (14 15) for detecting a current and/or current rise at the at least one DC source (12 13) and at least one controller (4) for influencing a direct current flowing in the respective motor phase of the DC power supply system if the current and/or current rise detected by the at least one current measuring device (14 15) is greater than a predeterminable current and/or current rise.
