Modeling of power cables for measurement calibration and PLC simulation up to 20 MHz

In many cases, the measurements taken in the grid to characterize the impedance, attenuation or emissions, require the placement of an extension cable to connect the measurement equipment to the connection point. When taking measurements, the extension cables used influence the measurement. This paper presents a methodology for characterizing the cables based on measurements and an optimization process that allows extracting a model based on primary cells placed in cascade. The methodology has been applied to extract the model for two different cables and validated with grid measurements. The first results show high concordance and support the validity of the methodology used. The cable models obtained by applying the proposed methodology will serve both to calibrate measurement systems and to simulate PLC systems.
