Ground wire
AnswerIt's a (lightning) protection wire, designed to protect the line conductors from lightning strikes
it meant for lightining protection and acts as grounding/earth wire
Theground conductor is usually grounded (earthed) at the top of the supporting structure, to minimize the likelihood of direct lightning strikes to the phase conductors.
Ground wires are bare conductors supported at the top of transmission towers.
Therefore D is my answer
If it is there to preserve for lightning strokes it has to be D: a ground wire
Guys sorry. but it is also create a "virtual" Faraday cage and only everything in the below angle of degree is protected.
The answer is D) acts as ground wire.
This conductor protect the line from lightening strokes. The charge produced by lightening is large in amount and they always choose the minimum path for discharge. So they get discharge by those conductor which fall earlier in their path. For this reason this conductor place on top.
D
Surely to act as "Ground Wire" or so called "Earth wire"
