Abstract: The oxidn. products of alkane-naphthene and aromatic chromatographic fractions vary in their effect on the dielec. properties of insulating oils. Trace amts. of oxidn. products of aromatic compds. of definite structure considerably increase the loss angle, but even higher concns. of alkane derivs. affected the loss angle to a lesser degree. Mixts. contg. complex aromatic-naphthenic compds. and more highly substituted aromatic hydrocarbons with long aliphatic chains showed optimum oxidn. stability and elec. properties.
