Abstract
As shown in Figure 3, the 60 Hz permittivity of the blend of naphthenic base oils used in this investigation decreased almost linearly with increasing temperature. Using available density /temperature data for a comparable oil as the basis for analysis, good correlation is obtained in relating the change in permittivity to change in density of the oil.
