“…This mineral oil is actually a liquid hydrocarbon, which has paraffinic or naphthalene structure and it is acquired through the fractional distillation of crude petroleum. Though it provides certain beneficial features like great dielectric strength, high oxidation stability, minimal viscosity and good heat transfer capability, it has low biodegradability i.e., < 25 % [1][2][3]. Due to the lack of availability and high cost of petroleum products, the price of mineral oil gets increased, which has promoted the researchers to focus on the natural insulating oil.…”

The application of Ceiba Pentandra Oil is introduced as an alternative to the traditional non-biodegradable insulation oil. Through the recent research in vegetable based insulation oil (coconut oil, palm oil, and olive oil), it is identified that the vegetable insulation oil is biodegradable but edible in nature, which leads to the food crisis. To prevent the insufficiency of food, an interesting non-edible oil is extracted from the seeds of Ceiba Pentandra, which has the capability of biodegradation. This work has focused on the utilization of Ceiba Pentandra seeds for the production of vegetable based insulation oil since it is considered as the sustainable energy resource and. A two-step chemical conditioning method and antioxidants are used to produce the Processed Ceiba Pentandra oil (PCPO). Adding to that, the insulation behavior of Processed Ceiba Pentandra oil (PCPO) with and without antioxidant is analyzed. The different concentrations of PCPO and naphthalene based Mineral oil mixtures have been compared as per the ASTM standard. The two-step chemical conditioning method has provided the enhanced behavior of physical properties like Viscosity, Acidity, Flashpoint, Fire points and AC breakdown voltage. While improving the oxidation stability, the electrical property like AC Breakdown voltage has met the dielectric Standards. Thus this Processed Ceiba Pentandra oil (PCPO) has the potential to be an alternative of traditional insulation oil.

“…Many studies addressing the development of vegetable oil-based transformer oils from various sources have considered palm oil, soybean oil, rapeseed oil, sunflower oil, castor oil, olive oil, corn oil, cottonseed, mustard oil, and coconut oil. [4][5][6][7][8][9][10][11] Additionally, vegetable oils also increased the transformer lifetime by 33% and insulation paper lifetime up to 5-8 times longer. 12,13 From a chemical point of view, mineral oils are made-up of four generic classes consisting of aromatic, paraffin, iso-paraffin, and naphthene, but only a proper portion of these compounds can attain excellent insulation properties.…”

The physico-chemical and electrical insulating properties of certain palm oil products, including triglyceride oils, fatty acids, fatty esters, and glycerol were evaluated for use in oil-immersed transformers. The studied triglyceride oils have excellent kinematic viscosity values: 30.25-40.49 mm 2 s À1 at 40 C, 6.46-8.34 mm 2 s À1 at 100 C; flash point: 278-320 C; moisture content: 16-175 mg kg À1 and dielectrical breakdown voltage: 29.1-40.9 kV. Fatty acids and fatty esters have relatively lower kinematic viscosity and flash point values than triglyceride oils. The type of hydrocarbon chain, hydrocarbon chain length and molecular size were shown to have substantial effects on the physico-chemical and electrical properties of the studied oils. The drying process imposed on refined-bleached-deodorized palm olein (RBD POo) has reduced the moisture from 400 mg kg À1 to 100 mg kg À1 and improved the dielectrical strength from 31.1 kV to 76.8 kV. Blending of RBD POo with fatty acids or fatty esters has improved the kinematic viscosity of RBD POo and offers even higher flash and fire points than mineral oil. This study showed that palm oil and palm oil products have strong potential to serve as coolants and may be safer for use in oil-filled transformers as compared to mineral oil.

“…Liquid insulation is widely used in high voltage system for the transformers where usually mineral oils are being used as an insulation. Mineral oils are poorly biodegradable and might vanish in the future [1]. The mineral based transformer oil is a non-renewable source and gives bad impact to the environment if it is unused or disposed because it is difficult to degrade [2].…”

This project aim is to investigate the breakdown characteristics of unused transformer oil and olive oil under AC and DC voltage at different temperature rate. HVAC and HVDC breakdown tests are carried out alongside with the hemisphere electrode arrangements. The high voltage test is done in order to observe the performances of the oil samples to attain the highest breakdown AC and DC voltages. In addition, this project needs to be done to see if olive oil as one of the vegetable oil can be an alternative for the conventional transformer oil. Commonly used transformer oil is made from mineral oil and it is declining day by day as its use increases. So as a precaution studies are done with vegetable oils to replace the mineral oil-based transformer insulation fluid. In this study, each oil sample is tested at different temperature rate and has recorded different value of breakdown voltage from the experiment. The gap distance between electrodes is constant and oil samples are heated at different temperature ranges. More voltage is needed to breakdown at higher temperature rate. Both the unused transformer oil and olive oil have linearly increased AC and DC breakdown voltages when subjected to higher temperatures. However, it is found that the highest AC and DC breakdown voltages are recorded at the highest temperature range and when the insulating medium used is olive oil. Moreover, the obtained AC and DC voltages are then be used to study the electric field in FEMM software.
