[EN] Partial discharge (PD) cable field tests require the use of high frequency sensors
coupled to the cable for PD apparent charge evaluation. PD sensors can be coupled to
the cable by magnetic field, like high frequency ...

[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 ...
The insertion of vertical slabs in a metallic rectangular waveguide distorts the power distribution of the waveguide, producing new modes and modifying the existing ones. The resulting waveguide, known as E-plane loaded ...

[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 ...
Theoretical results on sound transmission through plates perforated with compound periodic hole arrays are presented. Calculations are obtained by means of a model under the rigid-solid assumption, which is thoroughly ...
