Calculations of Short-Circuit Current Flows in Earth Wires of HV Lines
Journal Title: Acta Energetica - Year 2016, Vol 26, Issue 1
Abstract
This paper presents a method which enables calculating flows of short-circuit currents in earth wires of high voltage transmission lines, and its implementation in the form of a computer programme. The algorithm enables performing calculations for a double-fed line and star-connected lines (three terminal lines). The developed programme enables verifying dimensioning of earth wires in the context of their short-circuit thermal withstand value.
