Question: Calculate the conductor surface electric field strength in (mathrm{kVrms} / mathrm{cm}) for the single-phase line in Problem 4.32 when the line is operating at (20

Calculate the conductor surface electric field strength in $\mathrm{kVrms} / \mathrm{cm}$ for the single-phase line in Problem 4.32 when the line is operating at $20 \mathrm{kV}$. Also calculate the ground-level electric field strength in $\mathrm{kVrms} / \mathrm{m}$ directly under one conductor. Assume a line height of $10 \mathrm{~m}$.

Problem 4.32

Calculate the capacitance-to-neutral in $\mathrm{F} / \mathrm{m}$ and the admittance-to-neutral in S/km for the single-phase line in Problem 4.8. Neglect the effect of the earth plane.
