LA-110 Overhead Line Measurements in Santander, Spain

The dataset contains minute-resolution measurements collected from a pilot installation consisting of a single 3.5 m span of overhead line equipped with an LA-110 conductor. The pilot is installed on the rooftop of the "Escuela Técnica Superior de Ingenieros Industriales y de Telecomunicación" (ETSIIyT), Universidad de Cantabria, in Santander, Spain (43.472685° N, 3.799267° W). The span is oriented at an azimuth of 75°, measured clockwise from north. Measurements were recorded from 25 April to 25 September 2026, resulting in 219,758 observations. For each timestamp, the dataset provides the electrical, thermal, and meteorological variables required to characterize the operating conditions of the conductor: Column Description Unit timestamp_utc Observation time in ISO 8601 UTC - current Conductor current A temperature_conductor Conductor surface temperature °C temperature_ambient Ambient temperature °C wind_speed Wind speed m/s wind_direction Wind direction, measured clockwise from north ° irradiance Irradiance W/m² humidity Relative humidity % Missing observations were retained as missing values; no interpolation was applied. The dataset provides experimental data suitable for validating thermal models and benchmarking Dynamic Line Rating (DLR) approaches.
