Setting of Distance Relays on Lines Considering Weather Conditions from IEEE Standard 738

The distance relay is responsible for ensuring the protection and reliability of an electrical system. Some failures may occur due to inaccuracies in setting whether line parameters are not computed their entirety. Usually, literature does discuss influence weather conditions on cable temperature, which change impedance a line. Therefore, this work aims evaluate how current, ambient wind speed direction, azimuth angle directly affect adjustment. modeling has been performed Simulink, comparing results with without proper correction. figure out possible errors operation unwanted trips.
