    Transmission Line Design Information In these notes, I would like to provide you with some background information on AC transmission lines. 1. AC Transmission Line Impedance Parameters AC transmission is done through 3-phase systems. Initial planning studies typically only consider balanced, steady- state operation. This simplifies modeling efforts greatly in that only the positive … However, high-voltage AC transmission links have disadvantages, which may compel a change to DC technology: Inductive and capacitive elements of overhead lines and cables put limits to the transmission capacity and the transmission distance of AC transmission links.
