Patent ID: 8139383

Claim:
A power feeding station for delivering electrical power comprising: a low voltage side suitable for being connected to an electrical power source; a high voltage side suitable to be connected to a high voltage distribution power cable; a transformer for transforming the low voltage on the low voltage side to high voltage on the high voltage side; and a supervision system further comprising: a control function; a current sensor unit situated on the high voltage side for measuring characteristics of the current; means to receive characteristics of the current and means to deliver the characteristics of the current to the control function; safety rules suitable for governing the function of the control function; a circuit break unit situated on the low voltage side suitable for breaking the current; the control function further comprising means for receiving characteristics of the current and means for activating the circuit break unit and said control function configured to activate the circuit break unit based on the safety rules and the characteristics of the current; the transformer configured to deliver high voltage single phase alternating current on the high voltage side; and the high voltage distribution power cable operable to distribute current-symmetrical single phase current and suitable to be connected to at least one power receiving station for receiving electrical power.
