Question

Question: If the distance between conductors are large compared to the distances between sub conductors of each conductor, then the GMD between conductors is approximately equal to the distance between conductor centers.

(a) True (b) False

Short answer

Answer

Therefore, the correct option is (a): True

Step-by-step solution

Determine the expression for the GMD.

Let assume the single phase two conductor line in which number of the conductors are n and number of the sub conductor are m.

Let assume the distance between the conductor of x of 1^st and y of 2^nd conductor is .

The GMD is given by

Determine the distance between the sub conductors of each conductor.

If the distance between the conductors are large compared to the distance between the sub conductors, then distance would be equal to for all and .

$$\begin{gathered} GMD=\sqrt[mn]{D^{mn}} \\ GMD=D \end{gathered}$$

Hence distance between the conductor are large compared to the distance between the sun conductors of each conductors.
