The invention relates to an apparatus for supplying electrical power to a monitoring station which has, in particular, at least one sensor (6) and a radio transmission station (9). In this case, the monitoring station has an associated high-voltage line, in particular an overhead line catenary of the railway. Provision is made for the high-voltage line to be surrounded in an annular manner by a coil in which a current is induced, said current providing a supply voltage for the monitoring station, and in that the monitoring station is connected to a voltage tap on the coil. |
