Interests on nanomaterials for enhancing the insulation properties of dielectric liquid are growing in recent years. This paper presents experimental studies dealing with the influence of carbon nanotube (CNT) nanomaterials in AC breakdown voltages. The observations of AC electrical breakdown voltages of CNT disperse in mineral oil at 2.5mm gap distance were recorded. Five different amounts of concentrations...
The common insulating oil used in oil-filled transformer applications is mineral oil. In recent years, significant attention has been paid to alternative insulating fluids such as synthetic and natural ester liquids. The natural ester liquid is considered to be the best substitute of mineral oil in future. In order to apply natural ester liquid in transformers safely, it is important to have detailed...
Among the alternative fluids considered for application in transformers are Palm Oil (PO) and Coconut Oil (CO). Among the important studies that need to be carried out before it can be applied in-service is the lightning impulse performance. This paper presents the experimental work on the lightning impulse breakdown voltage of different PO, CO and Mineral Oil (MO). The PO used in this is the Refined...
