Numerical modeling of power cables

The paper presents numerical models developed in QuickField software to determine load capacity for single-or three-phase cables so that not to exceed allowable temperature limits. The models allow determining cables parameters: self and mutual inductances, self and mutual partially capacitances. As a result, the application of an optimized arrangement of cable can be used to make the temperature rise of cable as low as possible. Using transient magnetic model can determine under short-circuit conditions, the variations in time and consequently the peak values of the short circuit currents and of the electrodynamic forces.
