Question:

Figure 3.8 shows a single-phase line including two conductors ("2" and " 3 ") for sending and one conductor (" 1 ") for receiving power. The Geometrical Mean Radius (GMR) of each conductor is \(r^{\prime}\). Calculate the capacitance of the line in \(\mathrm{F} / \mathrm{m}\).

1) \(\frac{4 \pi \varepsilon_{0}}{2 \ln \left(\frac{D}{r^{\prime}}ight)}\)

2) \(\frac{2 \pi \varepsilon_{0}}{3 \ln \left(\frac{2 D}{r^{\prime}}ight)}\)

3) \(\frac{4 \pi \varepsilon_{0}}{3 \ln \left(\frac{D}{2 r^{\prime}}ight)}\)

4) \(\frac{4 \pi \varepsilon_{0}}{3 \ln \left(\frac{D}{r^{\prime}}ight)}\)
