The Effect of Temperature on the Breakdown Stress in Saturated Hydrocarbon Liquids

This work deals with the effect of temperature on the breakdownstress in saturated hydrocarbon liquids which include n-hexane, n-heptane and n-octane under the influence of non-uniform field created by using point-plate electrode geometry. It was found that in a range of room temperature there is no large effect of temperature on the value of breakdown field in comparison with a higher range. Also it was found that the number of carbon atoms in dielectric liquid has an effect on breakdown stress. Finally, it was found that the increase in the number of carbon atoms leads to an increase in breakdown stress as a definite result of increase in the viscosity of the dielectric liquid.
