This course provides a detailed technical examination of transmission line parameters used in electrical power systems, with emphasis on the calculation and practical significance of resistance, inductance, conductance, and capacitance in overhead 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.
As part of the calculation of resistance of lines, the skin effect influence and changes of resistance with temperature are covered in detail. 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 are applied to multiple 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.
Each topic is immediately followed by well-chosen numerical examples and detailed steps leading to their solution to further enhance the learning experience of the participants.
This course 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.
