Résumé

This study aims to investigate the AC and lightning impulse (LI) breakdown voltage performance of natural ester-based nanofluids enriched with fullerene (C60) nanoparticles, which stand out with their long-term stability and superior dielectric properties. The AC and LI breakdown voltages of these natural ester-based nanofluids with five different concentrations of fullerene (C60) are measured 30 times and the compatibility of these measurements with the statistical distribution is checked with the Anderson-Darling test. The AC breakdown voltage performances of 0.3 g/L and 0.4 g/L C60 nanofluids are 5.1% and 7.8% better, respectively, than natural ester. The LI breakdown voltage performance of 0.1 g/L C60 nanofluid is 8.2% better than natural ester. After accepting the conformity of these measurements with the statistical distribution, AC and LI withstand voltages are calculated at 1%, 10% and 50% breakdown voltage probabilities. The withstand voltages of both AC and LI nanofluids are better than natural ester in almost all samples at 1% breakdown voltage probability. The results show that natural ester-based C60 nanofluids can meet the electrical strength requirements of power system equipment with better AC and LI breakdown voltage performance.
