The non-uniform distribution of voltage across the units in a string of suspension insulators is due to:
1
Unequal self-capacitance of the units
2
The existence of stray capacitance between the metallic junctions of the units and the tower body
3
Non uniform distance of separation of the units the tower body
4
Non uniform distance of between the cross arm and the units
5
None of the above
