摘要

Electrical discharge on pressboard surface is one of the major failure mechanisms in power transformer. This study aims to analyze the effect of nanofluid on the electrical discharge at the surface of pressboard material used in power transformers under AC application. A needle to plane configuration with constant gap length was implemented on the surface of pressboard. First, the value and polarity of applied AC voltage during electrical discharge was measured in base transformer oil. Then, alumina nanoparticles were added with different weight fractions. The discharge behavior in nanofluids was obtained and compared with that of base oil. Discharge magnitudes for all nanofluid samples were better than that of base oil. The results were discussed in terms of surface charging of nanoparticles and its role in discharging phenomenon on nanofluid/pressboard surface.
