Abstract
In a circuit arrangement for automatic connection of a remote feed current path of a remote feed loop fed from both sides for electrical loads with direct current series feed, a parallel circuit of a first four-terminal network comprising two feed outputs and a second four-terminal network containing a connecting two-terminal network, controllable by current sensors, is provided for the acquisition of a feed output per remote feed current path, this being undertaken by way of diode current branches. The circuit arrangement can advantageously be employed for the remote feed of regenerators and communications transmission links.
