Abstract

The power transformer plays an important role in the electric power system. However, one of the main challenges associated with power transformers is their dielectric properties deteriorating over time. In recent years, researchers have explored nanofluid insulation as an alternative solution. The cellulose in the transformer will be damaged in the long term so these particles cause cellulose to become a contaminant in the transformer insulating oil. This paper proposes a test related to the Effect of Cellulose Paper on the Aging of Semiconductive Nanofluid Insulating Oil in Transformers so that this research can prove that the presence of cellulose paper particles affects the strength of the breakdown voltage that occurs during aging. The proportions of cellulose contamination in TiO2 (Titanium Dioxide) nanofluids of 0%, 10%, 25%, 50%, and 100% with aging times of 0 hour and 250 hours are compared in this paper. The strategy used is testing the distribution of particles, especially by testing the sedimentation and Particle Size Analyzer to determine the stability of the nanofluid and cellulose. The experimental results show that the less the amount of cellulose, the less amount of precipitate, and the longer the aging time, the more sediment that occurs. The breakdown voltage test was used to determine the insulating strength characteristics of TiO2 nanofluids when cellulose contaminants were present. The experimental results show that the more cellulose content is mixed, the less insulating strength will be and the longer the age of the nanofluid, the insulating strength will also decrease.
