The inductance of a power transmission line increases with
Right Answer is:
Increase in spacing between the phase conductors
SOLUTION
The inductance of transmission line is given by
$L = \dfrac{{{\mu _o}}}{\pi } \times \ln \left( {\dfrac{D}{{{r^\iota }}}} \right)$
Where
D = distance between the conductor
r’ = radius of the conductor
$L \propto \ln \left( {\dfrac{D}{{{r^\iota }}}} \right)$
Hence inductance is directly proportional to the distance between the conductor. If we increase the spacing between the conductors then inductance will also increase.
