Abstract: A method determines a fault location in a fault on an electric line. Accordingly first reference voltage values are determined by current and voltage sampled values at a first line end and an impedance of the line. Second reference voltage values are determined by current and voltage sampled values at a second line end and the impedance. Fictitious first reference voltage values are calculated using a wave guiding model, describing the wave response of the line, with the first reference voltage values. The fictitious first reference voltage values, in the fault-free case, correspond to the second reference voltage values at the second line end. Fictitious second reference voltage values are calculated with the second reference voltage values. The fault location is determined by the first and second reference voltage values and the first and second fictitious reference voltage values.

Abstract: A differential protection method for generating a fault signal includes measuring current measurements at least at two different measuring points of a multiphase transformer for each phase. The current measurements for each phase are used to form differential current values and stabilization values. The fault signal is generated if it is determined during a trigger region check that a measurement pair of at least one of the phases, being formed by using one of the differential current values and the associated stabilization value in each case, is in a predefined trigger region. In order to be able to selectively and reliably distinguish an external fault from an internal fault, the transformer has a grounded star point and a zero system current flowing through the star point is used to form the stabilization values. A corresponding differential protection device is provided for performing the differential protection method.

Abstract: A method protects an electrical modular unit from overcurrent damage by virtue of an inductive component converting electrical energy into magnetic and thermal energy, in which a bypass bypasses the inductive component during regular operation of the modular unit and current flows via the bypass. In order to reduce current spikes in the event of a surge current without significantly enlarging the semiconductor switching the circuit inductance for the commutation circuit, it is proposed that the bypass is opened by an overcurrent flowing through the bypass which is above a current value that can be achieved during fault-free operation of the modular unit, with the result that more current is forced through the inductive component than residual current flows through the bypass.
