Investigation of the electrical properties of palm oil (PO) under magnetic field applied and concentration doping of semiconductor particles in transfomer application

This paper presents a study investigating the potential use of Palm Oil (PO) as a transformer insulator medium by exploring its dielectric properties. The study includes evaluating the ac breakdown, tan delta test, and Raman measurement to assess the impact of doping various concentrations (0.01%, 0.1%, 0.2%, 0.4%, and 0.5%) of Silicon (Si) particles and influence of a magnetic field (0.01T) on PO's electrical properties. The results indicate that the dielectric properties of PO can be enhanced to make it suitable for transformer oil applications. This matter was proven when the doping of 0.1% Si particle with PO has the highest voltage breakdown value compared to the mixture with other Si concentrations. Hence it is higher than pure PO. Furthermore, it has been observed that the voltage breakdown of all samples is higher when a magnetic field is present, in contrast to the samples without any magnetic field applied. It's worth noting that the specific relationship between the magnetic field a voltage breakdown may vary depending on the material properties and experimental setup. However, further research is required to address additional crucial factors such as thermal stability, compatibility with transformer materials, and oxidation susceptibility of palm oil, ensuring its suitability as an effective insulator medium.
