Abstract :
Dynamic Thermal Line Rating (DTLR) is used to monitor and dynamically upgrade the existing power lines. The overhead conductor sag measurements using GPS has been used to evaluate DTLR in the present paper. GPS receiver BT359 has been used to measure overhead conductor sag of 440V power distribution line and DTLR has been determined at different air temperatures. The inherent error in raw altitude measurements obtained by GPS has been reduced using Least Square parameter estimation and wavelet analysis to obtain more accurate altitude measurements.
