Arrangement for the electric power supply of a consumer by means of a transmission path divided into two

Arrangement for supplying electrical power to a load by means of a transmission path which has been split into two parts The arrangement is intended to provide an isolated power supply for an electrical load ( 20 ). It contains a generator ( 30 ) for producing a supply signal (S 1 ), and a transmission path ( 40 ) having two separate branch elements ( 41, 42 ). The first branch element ( 41 ) is designed for transmission of the supply signal (S 1 ) in the forward direction, and the second branch element ( 42 ) is designed for transmission of the supply signal (S 1 ) in the backward direction, so that this results in a closed circuit for the supply signal (S 1 ). The two branch elements ( 41, 42 ) contain means for isolation (C 2 , C 3 ). The load ( 20 ) can be supplied by means of the supply signal (S 1 ) with an electrical power of at most 100 mW.
