Abstract Based on the importance of electrical transformers, it is very critical to ensure their reliability and continuity. This can be maintained by ensuring that their insulation system is reliable. Mineral oil is regarded as one of the primary insulations in transformers due to its abundance and coolant capability. Recently, researchers tended to improve the dielectric and thermal properties of conventional mineral oil using nanotechnology by suspension of nanoparticles into the base transformer oil in order to obtain transformer oil-based nanofluids. It is observed that there is a lack of studies investigating the impact of incipient faults on transformer oil-based nanofluids. Accordingly, this thesis aims to experimentally evaluate the performance of oil-based nanofluids under incipient thermal and electrical faults. In order to alleviate operator apprehension about using nanofluid-filled transformers and to ensure that traditional dissolved gas analysis (DGA) diagnostic techniques can still be applied if oil-based nanofluids are used in transformers. |
