Abstract

The power supply device includes electronic means (4) which are suitable to transduce energy from the power distribution line (3) during normal operating conditions and provide power to the protection unit (2). The distribution line can be low or medium voltage AC or DC and can also be single or three phase. A second electronic means (5) transduces energy from the line (3) during a current transient, such as a short circuit. An independent claim is included for a DC power distribution network.
