Abstract
An apparatus and a method for operating an electric power network are disclosed. The electric power network is a compensated network arranged to be compensated by an arc suppression coil. An indication for an occurrence of an earth fault in the electric power network is received and the arc suppression coil is tuned away from resonance with respect to a resonance point of the electric power network, while the earth fault is present in the electric power network, to increase fault current in the electric power network for tripping one or more relays in the electric power network.
