Dataset Supporting the Analysis of Synthetic Ester Material as an Alternative Insulating Oil for 20/0.4 kV Distribution Transformers Using MATLAB

Dataset supporting the analysis of synthetic ester material as an alternative insulating oil for 20/0.4 kV distribution transformers using MATLAB. The dataset contains transformer operating/reference profiles, aging acceleration factor (FAA) calculation results, insulating-oil test data, transformer ratio and winding-resistance test data, transformer-life results, and reported loss-of-life results. The dataset includes measured operating data, reference-profile data, laboratory measurements, transformer test measurements, and MATLAB/Simulink calculation outputs. Original data provenance is documented for each dataset component. Where discrepancies or ambiguous values were identified during data verification, the retained value follows the verified final model-input or reported-result series, while ambiguous values are preserved and flagged rather than estimated or silently corrected. The repository package is organized into six canonical dataset files together with a data dictionary, original data provenance, data verification audit, methodology notes, and this README. The dataset is provided to support transparency, traceability, and reproducibility of the reported analysis.
