Idmt earth fault

WebEarth-fault protection in solidly earthed HV & EHV system In solidly earthed systems the earth-fault cur-rents can be of the same order of magnitude as the short-circuit currents. By measuring the residual current the non-directional RXIDK 2H can be used as simple alternative of earth-fault protections for radial feeders and as back-up protections.
