Skin Effect and Proximity Effect in Transmission Line
In the skin effect, the flux set up in the conductor itself was considered and it was assumed that there is no other current carrying conductor nearby. This flux produces a nonuniform distribution of current in the conductor called skin effect. However, in the transmission lines, there are (one or two) current carrying conductors placed nearby and their magnetic flux …
