Abstract
Mineral oils play - in combination with cellulose (paper and pressboard), a vital part in the insulation system of large transformers and bushings. The dielectric stress within such insulation systems during high voltage direct current (HVDC) network operation is defined by a mixed stress that consists of AC, DC and transient components. Exemplary, the valve winding of converter transformers is to be named here.
