Energy distribution assembly with a control device and a current sensor

The power distribution system has a control device (5), where an electrical power source (10) and an electrical energy storage device (11) are connectable. The control device has an output line (18) which is connectable with a connection node (16) of a main line (15). The control device detects current values and voltage values present at each phase conductor (6) of the output line. A current sensor (12) detects a current in the main line between a local installation (3) and a public power network (1) on each phase conductor. An independent claim is included for a current sensor with a core enclosed in a coil.
