- Summary:
- ABSTRACT
In a search for mineral oil substitutes, we focus on silicone and ester oil. These
insulating oils are fire-resistant and environmentally friendly. In previous studies, we
investigated streaming electrification and dielectric breakdown phenomena in these
new oils and found that their performance was similar to or better than that of mineral
oil. In the present study, we focus on the thermal degradation of insulating oils.
Thermal degradation tests in the presence of a solid insulator and copper carried out
for 1000 h at 130 and 180 ºC. Color changes, chemical analysis and dielectric
breakdown characteristics were also investigated during thermal degradation of the
insulating oils. We also investigated the mechanical strength of the solid insulator. The
characteristics of aged oils were compared with those of fresh oils. Tested silicone oil
presents better performance than esters and mechanical characteristics of paper
remain unchanged in all resistance liquids.
