1. Consider a 3-phase transmission line. Its length is about 60 miles, and the average distance between two phases is 10 feet. The conductor type of the line is "Hen". Please determine X, , X and R of every one-mile long transmission line. (Hints: check the Table and examples on Lecture 6) 2. For the above three-phase transmission lines, what is the equivalent a model? Please plot the Y' equivalent a model. Second, specify Z' and using the above X, X, and so on. (Hints: The line is 2 of 60 mile long and belongs to the category of Medium Line) Is Z' TR + Vs Y' 2 VR
