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.
frequency or skin effect. 13.2.1 Frequency Effect The frequency of the AC voltage produces a second effect on the conductor resistance due to the nonuniform distribution of the current. This phenomenon is known as skin effect. As frequency increases, the current tends to go toward the surface of the conductor and the current density decreases
