Abstract

This article adheres to oil purity standards, investigating the impact of temperature, water, and carbon contaminants on transformer oils. The research employed breakdown voltage (BDV) and dissipation factor (DF) tests concerning IEC standards. Further, this article provided superior valuable insights into the behavior of transformer oils under different conditions and offered practical solutions for maintaining their optimal performance. The results highlighted that as temperature increased, the BDV of the oils decreased, underscoring the importance of maintaining adequate cooling in transformers. The presence of water droplets within the oil lowered the BDV and increased the DF. However, a treatment method involving a vacuum machine and nano-oil mitigated these adverse effects. Similarly, the presence of carbon atoms within the oil decreased the BDV and increased the DF. Still, the treatment method involving infrared radiation and titanium dioxide (TiO2) nanoparticles effectively improved the oil’s properties. In other words, the treatment method reduced carbon atoms’ effect on transformer oil through nano-oil, where the BDV and DF were performed on all samples before and after treatment to ensure the success of the treatment. Furthermore, a statistical analysis tool is employed to assess and evaluate the accuracy of the experimental test.
