| description |
The world’s energy requirement has been dominated by petroleum oil for
centuries in many application fields, including transportation, household, and
electricity. Mineral oil as an important insulating material in transformers has been
used more than 150 years. Mineral oil application in power system equipment can be
potentially hazardous to the environment especially when there are any incidents
during operational time like transformer explosion which may cause a spill of oil to
the soil or water stream. Due to the concerns about the deducing petroleum resources
and the environmental issues, the alternative insulating oil with biodegradable
characteristics has been attracted lots of attentions for a couple of decades. In this
thesis, the dielectric properties of a type of mineral oil (Transformer Oil) and a type
of vegetable oil (RBDPO) were investigated, and the effect of heating on their
dielectric properties were studied as well. Since the heating effects on the dielectric
properties of insulating oil, such as breakdown voltage, kinetic viscosity, pH Value,
In addition to the partial discharge performance under the heating condition was
studied. All the experiments in this project were conducted at a heating condition for
the temperatures of 25⁰C, 50⁰C, 70⁰C, and 90⁰C. RBDPO was compared with
petroleum based mineral oil. The results of experiments incorporated showed the
potential of oil as a substitute RBDPO to the petroleum-based mineral oil. The BDV
tests incorporated showed that the high BDV for RBDPO enables it to avoid a
breakdown when the electric stressed. The average value of the BDV increases
slightly as the increase of the temperature. The potential of RBDPO, as an electrical
insulating liquid, to replace the petroleum-based mineral oil also can be concluded
from the viscosity and acidity tests. From the experiments and analysis, it has been
proven that the RBDPO is a good insulation because the kinetic viscosity for
RBDPO is low and very near from the viscosity of the petroleum-based mineral oil
after heating the oil to 50⁰C and above. |
