Question

(a) What are the bundled conductors? Discuss the advantages of bundled conductors when used for overhead lines.

(b) The three conductors of a 3 - phase line are arranged at the corners of a right angled isosceles triangle. If each equal side of this triangle is $2\text{m}$, find line to neutral capacitance per $\text{km}$. Take the diameter of each conductor as $1.24\text{cm}$. The conductor are transposed at regular intervals.
