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
As temperature rises, the sag in transmission lines reduces
As
temperature rise, the sag in transmission line increase the tension in the
transmission line decrease.
Sag are two
types
(i) Catenary
(ii) Parabolic
Where,
Shape of sag
increases with the increase in the length of the span. For a small span (up to
300 m) parabolic method and large span (like river crossing) catenary method is
used for the calculation of sag and tension.
Hence, the
correct option is (B).
