Dielectric behaviour of natural and synthetic esters at inhomogeneous field conditions

Natural and synthetic esters will be more and more applied as an alternative fluid to the commonly used mineral oil. The application in electrical apparatus needs, at least, the same withstand ability against electrical breakdown or partial discharge (PD) activities as given by the...
