Abstract :
Mineral oil used in electrical applications for
insulation and heat transfer has a high flammability rate
and is non-biodegradable and thus dangerous for the
environment. This work is aim to examine the dielectric
properties of oil based on calabash seeds as a substitute
for mineral oil in power transformers. The dielectric
properties such as permittivity, conductivity and
dielectric losses were measured and the influence of
temperature and frequency factors on these is
highlighted. Dielectric spectroscopy is the main
characterization method used throughout this study. The
results show that calabash oil has a higher dielectric
constant (permittivity) than mineral oil. Dielectric
constant and dielectric loss of the studied oil decrease
with the increase in the temperature. Also, calabash
seeds oil has a lower conductivity at low temperatures. It
is suggested that calabash oil be used as a substitute for
mineral oil in power transformers.
