Kritische Betrachtung des Löschverhaltens in kompensierten 20-kV-Netzen

Emanuel Fuchs 11 Furthermore a new method for the automated evaluation of earth faults is introduced. The new method determines the detuning and the damping, based on the decay process, in the frequency domain. For the automated evaluation of earth faults the accurate registration of the distinguishing moment of an earth fault is necessary. For the accurate registration a new method is introduced in this work. This new method is based on the momentary frequency of the displacement voltage which allows the accurate determining of the distinguishing moment of an earth fault.
