Mutual Inductive Coupling in Power Distribution Systems

[splitendz]

Hi, I’ve just been reading about the mutual inductance coupling that can exist between adjacent conductors in a 3-phase power distribution system. I’m hoping to clear something up in my mind, if we want to model the imposed mutual impedance, is it represented as impedance between the lines (parallel) or can we represent it as additional series impedance on each phase?

Would my attached drawing be considered accurate assuming unequal spacing between conductors?

Thanks :) :)

No.
In general, the lines themselves are inductors.
You would distribute a series of capacitors between them.

Normally, you would find this kind of info associated with antenna feed lines.
The effect is small at the normal 50/60 hz electrical power frequencies.
