line capaticance

In a two-wire line, the potential difference is proportional to ln(D/r)

The potential of a conductor is proportional to charges in all conductors through the self and mutual elastances.

In the presence of the ground, self and mutual elastances can be calculated using am image conductor

In a three-phase transposed line, the line capacitance does not depend by the charge

Bundle arrangement increases the line capacitance

Zero-sequence capacitance is usually less than the line capacitance
