Abstract (en)
[origin: EP2380796A1] The railway vehicle has an induction loop (1) for verification of low resistive electric connection between wheels (115a-115d,116a-116d) of the railway vehicle and running rails (101,102). A feeder is provided, which connects the electric alternating current voltage to the induction loop in an intermittent manner such that the induction loop is supplied with temporal interruptions with the alternating current. The duration of the temporal interruption of the supply is longer than the duration of the supply of the induction loop occurred before the interruption. An independent claim is also included for a method for operating a railway vehicle.
