“…This is rather important in power line communication (PLC) applications [15]. On the contrary, the influence of the ground mode cannot be neglected in electromagnetic interference (EMI) problems [16], where the voltage potential is of interest rather than the voltage difference. The same conclusions can also be derived for complex three-phase cable configurations, with the additional intersheath modes presenting similar behavior as the ground mode.…”

In this paper various field test transient responses from a medium-voltage single-core cable lying on the ground surface are presented. The results from six different excitation cases are compared, applying the modal decomposition theory with the use of a complex-frequency-dependent modal transformation matrix. The resulting modal voltages present unique modal travel time and attenuation, leading to significant remarks about the wave propagation along the cable in each examined case. The decoupled voltages are also compared to the corresponding obtained from the assumption of a real-constant transformation matrix. Results are in good agreement, validating the use of the simplified modal transformation matrix for the calculation of high-frequency transient phenomena in single-phase cables with short lengths. The calculated propagation modes are eventually related with the voltage differences and potentials of the examined cable, revealing their significance in the study of various engineering applications.

“…This assumption is usually accurate enough for channel models for the NB PLC mode, considering also that the CM has a negligible influence on the transmitted signal in both WTW and WTG injection modes. However, the influence of the earth is significant for the calculation of EMI problems and in such cases a precise earth return model should be used [28]. As in the DM experimental setup in cases where the cable is terminated to a resistance higher than the CM characteristic impedance magnitude (>150 ), spectral notches and peaks are recorded at the same frequency.…”

“…The DM is associated with the transmitted signal propagation in both WTG and WTW coupling techniques [12,[25][26][27]. The influence of the CM in screen-bonded cable installations is significant mainly in electromagnetic interference (EMI) problems [28], where the conductor voltage potential to earth is of interest.…”

The vertex detector used in the upgrade of High-Energy physics experiment Belle II includes DEPFET pixel detector (PXD) technology. In this complex topology the power supply units and the front-end electronics are connected through a PXD power cable bundle which may propagate the output noise from the power supplies to the vertex area. This paper presents a study of the propagation of noise caused by power converters in the PXD cable bundle based on Multi-conductor Transmission Line (MTL) theory. The work exposes the effect of the complex cable topology and shield connections on the noise propagation, which has an impact on the requirements of the power supplies. This analysis is part of the electromagnetic compatibility based design focused on functional safety to define the shield connections and power supply specifications required to ensure the successful integration of the detector and, specifically, to achieve the designed performance of the front-end electronics.
