From , ,  the self inductance for one phase conductor
is given by (10)
* Phase conductor
lines are parallel current filaments of infinite length and infinitely small diameter.
Each sub-area should divided into mesh with the length of dx (1/8 of Xspan) in x direction and dy (10 m) in y direction (length of each sub-area is half of span length and width of each sub-area is a distance from center of line that the leaders outside of that distance will not strike the phase conductor
A closed form solution for three phase lines with polygonal phase conductor
arrangement has been derived in  by using double complex numbers with two imaginary units.
Emergency teams have established that a phase conductor
was broken, due to its twisting around the nieghboring post.
Simulation is carried out for movement of metallic particles in a three-phase bus duct with reduced phase conductor
diameter with a view to obtain optimum size of conductor for reliable operation.
The current in the neutral can actually be greater than the current in any of the phase conductors
. Especially for the "C" circuits, neutrals either need to be larger than the phase conductors
or separate neutrals are needed for each phase conductor
drop of a phase conductor
on a ground in overhead lines).
Explaining the ABC, the relevant officials told the meeting that it was overhead power line using several insulated phase conductors
bundled tightly together, usually with a bare neutral conductor.
