Title: Overload protection for communications system - has voltage arrester bridged by LF-pass inductor to neutralise atmospheric high voltages
Inventor: POPP ERWIN DIPL ING
IPC: H02H9/06
Filed: 1974-03-01
Abstract: The overload protection circuit, for communications systems, has a voltage arrester protecting the unit and shunted by an inductor whose transmission frequency lies outside the frequency band used by the unit. A series capacitor connects one end of the voltage arrester to the unit. This capacitor consists of two antiseries diodes connected together at their cathodes so that they present a low-resistance path when the system is operating normally. These diodes may also be thyristors. Two more diodes are connected antiparallel across the input of the unit. Since most excess voltages originating atmospherically in transmission cables have most of their energy at lower frequencies, the inductor smooths this energy without producing a response in the voltage arrester.
