Information

This function computes the overall capacity of a cable.

When the voltage level is medium or high, the cables have geometric parameters that can be used to compute the capacity as

C = l_CABLE 2 π ε₀/log(GMD/r),

where l_CABLE is the length of the cable, ε₀ is the dielectric constant of the air, GMD is the geometric mean distance, and r = d/2 where d is the inner diameter of the cable.
