In the study of physical phenomena transmission lines, power lines in the study of the parameters is essential. For example, in the flow calculation on the line, you know the line at 50Hz or 60Hz positive sequence parameters, during short circuit fault analysis system, you need to line the negative sequence parameters and zero-sequence parameters, while on the line transient when studies have only...
The paper deals with the evaluation of the characteristic impedance of a multiconductor transmission line with one conductor periodically grounded. The topic, even if not adequately discussed in literature, has a relevant application in the analysis of the role of the shield wire in power lines, in order to quantify the mitigation of induced overvoltages. The problem is here modelled, leading to a...
The relation between MTL (multiconductor transmission line) capacitance matrix and two-conductor isolated capacitance has not been systematically studied, so classical methods usually adopt complex and time-consuming micro-elements analysis to compute MTL capacitance matrix. To solve the problem, a novel method uses two-conductor isolated capacitance to construct MTL capacitance matrix on system-lever...
The effectiveness of a grounding system is highly dependent on several parameters such as its size, i.e. the length of the ground conductor, the electrical characteristics of the ground conductor and its surrounding soil. A single long horizontal ground conductor being a basic configuration of a grounding system could act as a path for the transient currents to be easily and effectively dissipated...
This study is carried out to determine a suitable excitation source that can be used to model the lightning return stroke on a single long horizontal ground conductor. It is used to determine the fastest results obtained for the transient response of a single long horizontal ground conductor and for computation efficiency purposes. In this study, three various excitation sources are used and been...
