Parallel lines 

High voltage transmission lines can be constructed of several parallel conductors, arranged on the same or even different towers. EA-PSM Electric allows to analyse transmission networks with parallel lines, create costume models of towers with phase, ground and lighting protection conductors as well as wire conductors. Advanced calculation algorithm takes into account mutual inductance and capacitance between each conductor, conductors and earth, thus, providing reliable results of the calculations in high voltage networks. From the power line model EA-PSM Electric will automatically calculate impedance of positive-, negative- and zero- sequences that are needed for the asymmetrical short circuit calculation.

Typical applications of the feature
  • High voltage transmission networks analyses
  • Voltage level related issues solving, like increased voltage due to capacitive coupling
  • Asymmetrical short circuits calculation
  • Protection coordination
