<p>An electricity distribution system for providing end user networks (K) with electricity, provided with a number of electricity distribution stations (D), and circuits comprising phase lines (5) and neutral lines (6) extending between the distributions stations (D) and end user networks (K),
wherein at at least one end user network at least one local earth electrode (W) is provided for earthing one or more local end user earthing conductors (8), wherein the local earth electrode (W) is electrically coupled to a respective neutral line (6) of the network;
wherein the system comprises a measuring device (M) for monitoring integrity of the neutral line (6) coupled to the earth electrode (W). The invention further relates to a method for adapting a TT-electricity distribution network.</p> |
