The designof a transmissionline dependson fourelectricalparameters:1. Seriesresistance2. Seriesinductance3. Shuntcapacitance4. ShuntconductanceThe seriesresistancerelies basicallyon the physicalcompositionof the conductorat a seriesinductance and shuntcapacitance are producedby the presenceof magneticand electricfieldsaround the conductors,and dependon shuntconductanceis due toleakagecurrentsflowing acrossinsulatorsand air.
Once evaluated, the line parameters are used to model the transmission line and to perform design calculations. The arrangement of the parameters (equivalent circuit model) representing the line depends upon the length of the line. 2006 by Taylor & Francis Group, LLC.
