Time-harmonic impedance tomography using the T-matrix method
IEEE Transactions on Medical Imaging, 1994A time-harmonic formulation for the electrical impedance tomography (EIT) inverse problem accounting for electrodynamic effects is derived. This work abandons the standard electrostatic impedance model for a full-wave T-matrix model. The advantage of this method is an accurate physical model that includes finite frequency effects, such as diffusion ...

Probabilistic evaluation of harmonic impedances in unbalanced distribution systems
2003 IEEE Bologna Power Tech Conference Proceedings,, 2004This paper presents a technique to obtain the probability density functions of network harmonic impedances in an unbalanced three-phase distribution system. In these systems the impedances can significantly vary as a function of time due to the presence of single and multi-phase capacitors, generators and filters which can be switched on and off and ...

Guide for assessing the network harmonic impedance
14th International Conference and Exhibition on Electricity Distribution (CIRED 1997 - Distributing Power for the Millennium), 1997The objective of this report is to provide practical guidance for assessing power system harmonic impedance, taking into account the considered network voltage (LV, MV or HV), the disturbing load importance (small or great contribution to the power network pollution) and the analytical and computational tools available.
