                  abstract = {Dynamic Line Rating (DLR) offers a practical means of improving the use of existing transmission infrastructure where Static Line Rating (SLR) may underestimate actual line capacity under favourable weather conditions. This study evaluated the effectiveness of DLR in enhancing transmission capacity, system security, and economic operation of the IEEE 118-bus power system. A weather-based DLR model was developed for the selected branch 141 between buses 89 and 92, and its performance was compared with SLR over 24 hourly weather intervals. The assessment covered line loading, voltage profile, active power losses, congestion, operating cost, N-1 contingencies, and uncertainty. Results showed that DLR increased line capacity by an average of 49.59%, with improvements ranging from 8.06% to 82.91%, while congestion reduced by 87.50%. Voltage profile, losses, and operating cost remained essentially unchanged. All 177 connected N-1 contingencies converged, although some post-contingency overloads remained. The uncertainty-informed 5th-percentile rating of 751.34 A exceeded the static rating of 709.88 A. The study recommends combining DLR with reliable weather monitoring, uncertainty margins, and N-1 security assessment for safe operational application.},
