[2]. PE Civil Breadth Exam (Morning Session)-120 Solved Problems update-2021 exams. The shape of sag increases with the increase in the length of the span. For a small span ( up to 300 meters) parabolic method and large span ( like river crossings) catenary method is used for the calculation of sag and tension. Conductor weight – Sag of the conductor is directly proportional to its weight. calculation of the dip magnitude can be made more accurate by implementing a calculation method called Moving Fault Node. Calculation of Sag: The sag & tension of conductor may be calculated in the following condition:-. towers of the same height) is called level span .
