PowaLine® is used to calculate overhead powerline conductor impedances, current carrying capacities and fault withstand capacities: 

  • Impedance - The impedance application calculates the positive and zero sequence resistance, reactance and susceptance for various configurations of three phase overhead lines.

  • Current carrying capacity - The current carrying capacity application calculates the phase and earth conductor rating currents for various atmospheric and conductor conditions. 

  • Fault withstand capacity - The fault withstand capacity application calculates the withstand times for phase and earth  conductor faults for various operating temperatures.
