To eliminate local corona and reduce minimal discharge distance of transmission lines, this paper analyzed expanding diameter insulation jacket for 110kV transmission line. The minimal discharge distance and its relationship with the diameter of semi-conducting and expanding diameter was calculated theoretically, finding the best size of expanding diameter and general standard of expanding diameter...
This document presents the analysis of impedance, tension, and electricity variables facing impulse discharges on the guard cable in a transmission line, in which we consider different grounding systems modeled in software ATP/EMTP using the Distribution and Tensioning Factors method (DTF). The methodology is divided in four stages: tower model selection, equivalent circuit for the grounding system,...
This paper presents the behavior of a grounding mesh in presence of a high-frequency overvoltage transient caused by switch closing in electrical substations and atmospheric discharges. The simulation of the mesh is based on Transmission Line Method (TLM). The output of the simulation is the sum of induced and conducted currents caused by such high-frequency overvoltage input in some spot of the mesh...
