Consider a bundled conductor of an overhead line, consisting of three identical sub-conductors placed at the corners of an equilateral triangle as shown in the figure. If we neglect the charges on the other phase conductors and ground, and assume that spacing between sub-conductors is much larger than their radius, the maximum electric field intensity is experienced at
-
- Point X
- Point Y
- Point Z
- Point W
Correct Option: B
Electric field intensity at various points are shown as fallows: 
It is clear from the above diagrams that minimum cancellation of vectors occurs at the point Y, hence maximum electric field intensity.
