Key Concepts of Transmission Line

Inductance

Flux linkage of a conductor in a group of conductor

Case-i: Single phase two-wire system.

Case-ii: Radio interference in the communication line.

Case-iii: Inductance per phase of the 3 phase transmission line.
Case-iv: Inductance per phase of a bundled conductor.
Case-v: Inductance per phase of a double circuit line.

Capacitance

The voltage between the conductor in a group of conductor 
Case-i: Single phase two-wire line.
Case-ii: Three-phase translated line.
Case-iii: Triangular configuration.
Case-iv: Bundle conductor.
Case-v: Double circuit line.
