Cable impedance data

posted on 2014-08-14, 12:27 authored by Andrew J. Urquhart, Murray ThomsonMurray Thomson
This dataset contains impedance data for low voltage electricity distribution cables. The data has been generated using a finite element modelling method based on the FEMM software package. The cable impedance data allows for the non-circular geometry of the sector-shaped conductors, and also takes into account induced eddy currents. Results are presented for 50 Hz and for harmonic frequencies up to 3 kHz. The impedance data provides the series impedance for six variants of Waveform cable, as follows: 3-core 95 mm², 3-core 185 mm², 3-core 300 mm² 4-core 95 mm², 4-core 185 mm², 4-core 300 mm² The dataset also includes details of the equations developed to describe the sector-shaped conductors, for use in entering the cable geometry into the FEMM software.
