1. A device for supplying energy to a sensor arrangement in a rail vehicle, wherein a first electrical conductor connects a motor of the rail vehicle, the device comprising:
a second electrical conductor having an inductive coupling to the first electrical conductor that connects the motor of the rail vehicle, and said first electrical conductor being at least part of a motor cable connecting a converter to the motor;
a switching module to be operated by an operating voltage, said switching module being configured to process signals of at least one sensor for acquiring data and/or a state of a vehicle component of the rail vehicle, and said at least one sensor being part of a sensor arrangement and said switching module being connected to the sensor arrangement or forming a part of the sensor arrangement;
said switching module being connected to said second electrical conductor, and second electrical conductor being configured to generate the operating voltage for said switching module from an alternating voltage carried by the first conductor, by way of induction in said second electrical conductor; and
at least one segment of said second electrical conductor being formed as a winding of a coil, and said coil having an annular core and said core surrounding the first electrical conductor concentrically.
