摘要： The network area (15) comprises a first electrical transformation centre (3), at least one second electrical transformation centre (20) and electric power generation equipment (2) configured to feed, when the network area (15) is insulated from the rest of the high voltage network, a first low voltage distribution network. This equipment (2) is connected to a low voltage side of the first centre (3) to feed the network area (15) through at least one transformer (4). The fault protection system (1) is installed between a high voltage side of the first centre (3) and a low voltage side of said centre (3) in a position preceding the electric power generation equipment (2), and configured to detect a ground fault and to issue an order for the electric power generation equipment (2) to stop operating.
