Fault Current Distribution in Transmission and Distribution Systems with Shield Wires, Neutral Wires and Cable Sheaths

摘要：

The fault current distribution among various paths, such as shield wires, neutral wires, cable sheaths, electric line structure grounds, and substation or power plant grounding systems, is computed and analyzed for several scenarios. A parametric analysis of the effects of several key variables on the fault current distribution is carried out. The variables include: cross section of power lines, length of power lines, tower footing resistance, grounding system resistance, type of static wires, and soil resistivity. In this paper, the fault current distribution and electromagnetic interference levels have been studied and evaluated for a typical electrical network with overhead and underground cable lines. Furthermore, a measure has been provided to effectively reduce interference to acceptable levels.
