The sag of a transmission line is least affected by
Self weight of the conductor
Temperature
of the surrounding air
Current
through the conductor
Ice
deposited on the conductor
Current
through the conductor
In a transmission line sag is defined as the vertical difference in level between point of support and the lowest point of the conductor.
Where L-
Length of the span
W - Weight
per unit length
T - Tension
in the conductor
Hence, the
correct option is (C).
