Abstract (en)
[origin: WO03078997A1] The invention relates to a device for earthing a diagnostic installation of wheels of electrically driven rail vehicles, using electromagnetic ultrasonic wave transducers. Said device prevents the coupling of interference emanating from the vehicles into the ultrasonic testing heads, whilst maintaining the underlying functional principle of the test method, without the need to interfere with the vehicle devices. The track section in the spatial working area of the ultrasonic test is galvanically isolated from the electric potential of the neighbouring track areas and comprises in addition an earth that is buffered against high-frequency interference currents.
