Abstract:
The
world’s
energy
requisite
has been
controlled
by
petroleum
oil for
a long
time in
transportation,
household
and
power
sectors.
Mineral
Transformation
Oil (MTO),
being an
essential
insulating
material
in
transformers,
has been
used for
over
fifteen
decades.
MTO
application
in the
power
sector
could be
hazardous
to the
environment,
especially
during a
transformer
explosion
which
may
cause a
spill of
oil to
the soil
or water
stream.
Owing to
the
threat
of MTO
to
environment
aspects,
alternative
insulating
oil with
biodegradable
characteristics
has
attracted
a lot of
devotions
in
recent
studies.
To
validate
the
aptness
of using
Purified
Papaya
Seed Oil
(PPSO)
as an
insulating
fluid in
an
electric
transformer,
it is
vital to
compare
dielectric
properties
of PPSO
with
that of
MTO
insulating
liquid.
This
study
presents
a
comparison
of
temperature
effect
on
dielectric
properties
of PPSO
with the
MTO
insulating
liquid.
Breakdown
voltage,
dissipation
factor
(tan δ)
and
dielectric
constant
were
measured
by
existing
established
testing
standards.
The
breakdown
voltage
was
determined
by IEC
156
standard
test
method,
whereas
the
dissipation
factor
and
dielectric
constant
were
determined
based on
IEC
60247
standard
test
method.
The
results
revealed
that the
variation
of
dielectric
properties
of PPSO
due to
temperature
change
was
similar
to that
of MTO.
However,
the
dissipation
factors
and
breakdown
voltages
of
dielectric
properties
of PPSO
were
better
when
compared
with
those of
MTO at
higher
temperatures,
but with
a slight
decrease
in
dielectric
constants
with the
increase
in
temperature.
