Abstract

Abstract Translated from German Zur Verringerung von Schaltungsaufwand und Verlusten bei Doppel-Hochpässen für Filteranordnungen in Netzen mit hohem Spannungsniveau sind die beiden Resonanzfre­quenzen und Güten des Doppel-Hochpasses so abgestimmt, daß im kritischen Oberschwingungsbereich höchstens eine geringe unschädliche Resonanzüberhöhung auftreten kann, wozu ein Reihenkondensator (C R ) samt einer Reihen­drossel (L R ) in Reihe zu einer bei Hochspannung geer­deten, bei Mittelspannung freien Parallelschaltung aus ohmschen, induktiven und kapazitiven Schaltungs­elementen (R P , L P , C P ) an das Netz angeschlossen sind. In order to reduce circuit complexity and losses in the case of double high-pass filters for filter arrangements in networks with a high voltage level, the two resonance frequencies and qualities of the double high-pass filter are coordinated in such a way that in the critical harmonic range at most a small harmless resonance increase can occur, for which purpose a series capacitor (C R ) together a series choke (L R ) in series with a parallel connection of ohmic, inductive and capacitive circuit elements (R P , L P , C P ) which are grounded at high voltage and free at medium voltage are connected to the mains.
