Claim:
1. A method of determining a topology information item on and controlling a low-voltage electrical distribution system, wherein low voltage is a voltage within a household, the method comprising: (a) selecting a group of at least two current-measuring devices arranged at mutually different points in the low-voltage distribution system; (b) measuring a current with each of the current-measuring devices so as to form respective current measurement values; (c) adding the current measurement values so as to form a current sum taking into consideration a current flow direction; (d) forming a topology information item, which specifies that the current-measuring devices electrically isolate a load-free and source-free section of the low-voltage distribution system when an absolute value of the current sum falls below a predetermined threshold value and using the topology information item formed to control the low-voltage distribution system.
