Through New Electric Power Technology No. 75, an overhead transmission line measurement technology using space vectors, KEPCO KPS measures sag and calculates the actual tension values of power lines to verify whether the statutory safety factor requirements are satisfied.
Based on structural analysis review results, KEPCO KPS identifies members or bolts that do not meet the required safety factor and proposes reinforcement, replacement, or specialized construction methods depending on site conditions.
