“…According to previous works, palm based oil has a wide range of viscosity [14,15,[20][21][22][23][24][27][28][29][30] Table 2 [25,26]. The viscosity of RBDPO could be further reduced by reducing the amount of fat content [24,27].…”

“…PKO has much wider range of carbon number ranging from 8 to 18 while for CPO, the range of carbon number is between 14 and 18. Fatty acids with a carbon number from 8 to 16 are saturated acids while fatty acids such as Stearic acid, Oleic acid and Linoleic acid are known as unsaturated acids [14,15].…”

“…Types of palm based oil Viscosity (mm 2 /s) at 40°C CPO [30] 25 at 50°C RBDPO [23,24,27] Between 37 and 50 RBDPO Olein [28,29] 21 PKO Alkyl ester [20,22] 3.2 to 6.99 at 20°C PFAE [14,15] 5.06 Natural ester [25] 33 Synthetic ester [26] 28 RBDPO Olein, PKO Alkyl Ester and PFAE have much lower viscosity than natural ester and synthetic ester. The viscosity of CPO and RBDPO Olein are much better than RBDPO possibly due to the fatty acids composition.…”

“…The chemical characteristics of palm based oil are almost close to natural ester such as it is biodegradable, has high flash/fire point and it is non-toxic since most of the palm based oil is from the food grade type [13]. Palm based oil has also a wide composition of fatty acids that include a wide range of carbon which account to the good oxidation stability as compared to other types of vegetable oils [14,15].…”

-Mineral oil has been widely used as dielectric insulating fluid in transformers due to its excellent performance in-service. However, there are few issues with mineral oil such as it has poor biodegradability and could contaminate the environment if a spillage occurs. With the increasing tight regulation on safety and environment, alternative fluids for mineral oil are currently being investigated and among the suitable candidate is the vegetable oil. There are different types of vegetable oils and one of them is the palm based oil. At the moment, extensive research works are carried out to examine its feasibility to be applied in transformers. This paper will review the previous research works that were carried out to examine the suitability of palm based oil as dielectric insulating fluid in transformers. The physical and chemical properties of palm based oil are studied based on viscosity, acidity, oxidation stability and flash point. Next, the electrical characteristics of palm based oil are examined based on AC breakdown voltage, relative permittivity, dissipation factor and partial discharge.
