Abstract
A method generates an error signal indicating the location of a ground fault in a line between two line ends. A voltage and a current are measured at both ends of the line, establishing measured values, and the location of the ground fault is determined when or after a ground fault is detected. Accordingly, harmonic indicator variables are established and used for determining the location of the ground fault.
