The exact knowledge of the grounding system impedance, including its expected variability, is a matter of paramount importance in the design of medium and high voltage infrastructures. The principles underlining the physical ...

[EN] High frequency current transformers (HFCT) are now widely used for partial discharges detection and measurement, specially for partial discharge location and source identification. However, many difficulties arise due ...

[EN] This paper presents a model for simulating vehicletrack interaction at high frequencies for investigations of rail roughness growth. The dynamic interaction model developed employs a substructuring technique and the ...
