Magnetic field shielding of underground cable duct banks
(2013)
In this paper an in-depth parametric analysis of shielding effectiveness obtained when using ferromagnetic or conductive screens to mitigate the field generated by duct banks is presented. Due to the need of a case-by-case ...

Application of nonlinear Kalman filters to the identification of customer phase connection in distribution grids
(Elsevier, 2021-02)
This paper presents a state estimation approach to address the problem of identifying the phase to which single-phase customers are connected in three-phase distribution grids. The proposed method performs Kalman filtering ...

Voltage Quality Factor for Networks Supplying Unbalanced Nonlinear Loads
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2005)
While the common term for describing the harmonic content and the unbalanced loading of the three-phase supply is power quality, it is actually the quality of the voltage that is being addressed in most cases. The power ...
