Line Sag & Tension Analysis

Transmission & Distribution Overhead Lines ETAP Transmission & Distribution Line Sag and Tension Analysis module is an important tool to perform sag and tension calculation for transmission and distribution lines to ensure adequate operating condition for the lines. If the tension applied on a line is beyond its limit, the line conductor could be damaged, and the transmission capacity and life span of the line will be reduced. If the sag is too large, it may cause a short circuit between the line and objects below it or a short circuit between lines in extremely windy conditions.
