NettetIn North America, power lines are usually 115 kV, but 230 kV is also common. You can determine the voltage level of a line by observing the distance off-center of the supporting tower from adjacent structures. If you notice, one tower is lower than its companion, and it leans to one side. This is because 115 kV power passes through a line. Nettet12. sep. 2024 · The voltage reflection coefficient going from 50 Ω transmission line to a 75 Ω load is Γ = 75 − 50 75 + 50 = + 0.2 The fraction of power reflected is Γ 2 = 0.04, which is 4%. The fraction of power transmitted is 1 − Γ 2, which is 96%.
