A transmission line is a series of conductors, often but not necessarily two, used to guide electromagnetic energy from one place to the other []. It''s that simple. The more complicated part is the math behind it (Maxwell''s Equations; see Appendix E) because we no longer consider a transmission line a lumped-element RLC network (see Fig. 7.9 ).

What is transmission''s role in the clean energy future?
Increasing the capacity of existing transmission interconnectors or high voltage lines can lead to more customers accessing cheaper and more reliable electricity. This creates more competition in the electricity wholesale market, leading to lower wholesale electricity prices and therefore lower electricity bills to consumers.
Theory of Transmission Lines | SpringerLink
On a lossless transmission line, SWR = 5 and Z 0 = 50 Ω. To identify the conditions on the line, three measurements are made by sliding a voltmeter along the line.
