Modelling Aspects of Sheath Bonding in Medium- Voltage Cable Systems: Operational Condition

The accurate modelling of underground cable systems and specifically of sheath bonding designs in system studies is very important. This paper systematically investigates different modelling issues regarding the calculation of sheath currents and voltages at power frequency in cable systems. A parametric steady-state analysis is performed using the ATP/EMTP software. The results of the investigations reveal some important issues regarding the accurate modelling of medium-voltage cable systems.
