An apparatus for the localization of a fault on a line wherein there is formed from at least one measurement signal derived from a line voltage and at least one measurement current derived from a line current an evaluation signal characterizing the direction and/or distance of a fault location with respect to a reference location on the line determinable by at least one regulation or adjustment magnitude, the apparatus comprising a voltage- and current measuring device provided at the measurement location and a signal processing- and evaluation circuit. The signal processing- and evaluation circuit possesses at least one reference location-adjustment input and there is provided means defining an operative connection, which changes the momentarily effective reference location adjustment, between an output of the evaluation circuit and the reference location-adjustment input.
