Insulating properties of vegetable oils and their blends

Nowadays researches on the viability of using vegetable-or plant-based oils in power transformers are gaining much attention due to the excellent biodegradability and good dielectric properties they possess. However, studies on their long-term ageing properties and improvement on their dielectric pr...
