Abstract

Bei dem kapazitiven Trennglied zur galvanischen Trennung eines Koaxialkabels [42] ist zusätzlich zu einem Trennkondensator [A] im Außenleiter ein Hochfrequenzfilter, vorzugsweise ein Tiefpaßfilter vorgesehen, mit dem die Abschirmeigenschaften des Trenngliedes wesentlich verbessert werden. Der Trennkondensator im Außenleiter kann Teil des Hochfrequenzfilters sein. Durch mehrere kaskadenartig ge­ schaltete Hochfrequenzfilter können die Dämpfungseigenschaften des Trenngliedes noch weiter verbessert werden. With the capacitive isolating element for galvanic isolation of a Coaxial cable [42] is in addition to a separation capacitor [A] in the Outer conductor a high-frequency filter, preferably a low-pass filter provided with which the shielding properties of the isolator be significantly improved. The isolating capacitor in the outer conductor can Be part of the high frequency filter. Through several cascades switched high-frequency filter can reduce the damping properties of the Isolator are further improved.
