SSC JE Electrical Engineering 24 Jan 2018 Evening Paper

Question : 167 of 200

Marks: +1, -0

Which of the following statement is incorrect?

As the temperature rises, the tension in the transmission line decreases
As temperature rises, the sag in transmission lines reduces
Tension and sag in transmission lines are complementary to each other
None of these

Solution:

Sag ‘S’ =

{WL^2}/{8T}

T = Tension in a conductor
W = Weight of conductor
L = Span length
If temperature increases then tension in conductor Decreases. If tension Decreases the Sag increases.
