The aim of this paper is to present the tasks accomplished so far in a research project dealing with the electromagnetic modelling of a railway line. The project is briefly presented, and the propagation and radiation modelling of a uniform multi-conductor line above soil through the transmission-line theory is discussed. Finally the model is validated through comparisons with experimental data...

Deduce the differential equation for current (or voltage) in a two-conductor transmission line that is characterized by resistance R (summed over both conductors), inductance L, capacitance C and leakage conductance K, all defined per unit length. The leakage conductance describes the undesirable current Ileakage (per unit length) that flows directly from one conductor to the other across the d...

Since past investigations have shown that radio frequency (RF) signal transmission in the bore of a railgun can be practical, the feasibility of using time domain reflectometry and well-established transmission line theory is investigated as a means to determine armature position during launch. This report describes the transmission line model of the HEMCL and initial measurements suggesting th...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...
