What is the economic voltage between lines in 3-phase system where V is the line voltage in kV, L is the distance of transmission line in km and P is the maximum power per phase to be delivered in a single circuit?
1
\(V = 5.5{\left( {\frac{L}{{1.6}} + \frac{{3P}}{{100}}} \right)^{0.5}}\)
2
\(V = 5.5{\left( {\frac{L}{{0.62}} + \frac{{3P}}{{100}}} \right)^{2}}\)
3
\(V = 5.5{\left( {\frac{L}{{0.62}} + \frac{{3P}}{{100}}} \right)^{0.5}}\)
4
\(V = 5.5{\left( {\frac{L}{{1.6}} + \frac{{3P}}{{100}}} \right)^{2}}\)
