Calculation and validation of sector-shaped conductor cable parameters in LV distribution systems

Abstract

The exact determination of faults in underground power distribution networks requires accurate cable parameter data. Accuracy depends on how the cable parameters have been derived, which in turn is a function of the core shape. This paper schematically highlights an approximate transformation of the sector-shape core into a circular shape that is needed for simulation. Then the available multi-core circular shape cable expressions are elaborated for calculation of the cable impedance and admittance matrices. The computed parameters of the four sector-shaped core cable are verified against those obtained in PSCAD-EMTDC and EMTP-RV simulation software, as well as with those provided by the manufacturer that comply with the BS7870. The results show that the presented cable parameter calculation approach is robust and reliable.
