Each station is represented by the following figures: · Figure 1 Willow Substation -Single Line Diagram Figure 2-Knik Arm Substation-Single Line Diagram Figure 3-University Substation-Single Line Diagram Figure 4-Ester Substation-Single Line Diagram The substations are part of the 345-kV transmission system and serve as inter- mediate switching stations or as terminal stations at the major load centers. The single line diagrams depict a 11 breaker-and-a-half 11 arrangement of the sta- tion and also stww the proposed relay protection schemes for transmission line and major equipment.
