So for inductance of transmission line book says formula
H = 2 * 10 -7 Loge { [Ds]/[Dm] }
I'm struggling to understand self and mutual geometric mean distance.
Here is one solved example
and for this they've drawn
And they say that let a a' form one connection and let b b' form other connection.
I'm struggling to understand how are they in parallel.
Current will go from a and return from a' or return from b?
How can b and b' be return path? As per question two upper and two lower conductors are in parallel so it means a and b are in parallel. So current in a and current in b have to be same.
And in three phase there are conductors r - r', y - y', b - b' So does this mean r and r' are in parallel or is it like current goes from r and returns from r' at one instant.
