Device for earthing diagnostic installation of rail vehicle wheels has track section in spatial working area of ultrasonic test galvanically isolated from electric potential of the neighboring track areas

摘要

The device has electromagnetic ultrasonic wave transducers. The track section in spatial working area of ultrasonic test is galvanically isolated from electric potential of neighboring track areas and comprises in addition an earth that is buffered against high-frequency interference currents and the earthing is isolated from opposite external electric influence and from internal short circuits.
