“…Divakaran et al [39] also studied and investiagted thermal charactiritics of mineral oil (virgin and aged) and vegetable oils (virgin and aged) and the result showed vegetable oils have better thermal performance. Coconut and palm oil have safe fire, flash pints, fire point and viscosity as shown in Figs.…”

“…The results indicated that corn and canola oils exhibit higher AC breakdown voltage than mineral oil. Divakaran et al [39] investigated impulse voltage, other electrical and thermal characteristics of virgin and aged vegetable oils and showed that vegetable oils have better insulation performance. Coconut and palm oil have better dielectric strength, viscosity, safe fire and flash points and impulse voltage properties superior to mineral transformer oil.…”

“…It has been found from Ref. 25 that production of acetylene and hydrogen under arcing condition for mineral oil is much more compared to the vegetable oil. But the production of CO and CO 2 , due to the breaking of carbonyl group-COO, is much more for vegetable oil in comparison to mineral oil.…”

Insulating liquid plays an important role for the life span of the transformer. Petroleum-based mineral oil has become dominant insulating liquid of transformer for more than a century for its excellent dielectric and cooling properties. However, the usage of petroleum-based mineral oil, derived from a nonrenewable energy source, has affected the environment for its nonbiodegradability property. Therefore, researchers direct their attention to renewable and biodegradable alternatives. Palm fatty acid ester, coconut oil, sunflower oil, etc. are considered as alternatives to replace mineral oil as transformer insulation liquid. This paper gives an extensive review of different liquid insulating materials used in a transformer. Characterization of different liquids as an insulating material has been discussed. An attempt has been made to classify different insulating liquids-based on different properties.
