Transmission Line Parameters
This engineering online PDH video presentation will present the theory and calculation of fundamental transmission line parameters.
This course explores calculation of the fundamental electrical parameters of transmission lines. Equations for calculation of line series resistance, series inductance and shunt capacitance are presented and detailed application of the equations are included in the many examples that follow the theoretical points. These equations are based on the physical characteristics of aerial lines, such as conductor material, size, length and configuration.
This course covers in details a part of calculation of resistance of lines, the skin effect influence and changes of resistance with temperature. Shunt conductance is discussed as well as factors influencing this parameter and its effect on performance of transmission lines. Series inductance and inductive reactance of lines are calculated for many representative line configurations, including for the case of bundled conductors. Shunt capacitance and shunt admittance between lines and between line and neutral are calculated, and the results applied to multiple different configurations of lines, including for the case of bundle conductors. Effects of bundling on the line series inductance and shunt capacitance are demonstrated through appropriate numerical examples.
This 2 PDH online video presnetation is intended for electrical engineers, as well as design personnel who are interested in learning about calculation and evaluation of fundamental parameters associated with aerial three-phase transmission lines.
