Description: Perform
analysis of oil samples.
SUMMARY
Two (2) samples of electrical
insulating oil were provided for analysis.
One sample
had been
“contaminated” with the customer’s two-part sealant (S-22).
The sealant was injected into the
oil and allowed to cure. The oil was
then analyzed.
Both samples were analyzed for
dissolved gas content to determine if the presence
of the
sealant in transformer oil would generate additional combustible gases.
Results are provided for both sets
of tests and there is no noticeable change in the
total
combustible gas content.
Carbon Dioxide, Nitrogen and Oxygen
are non-combustible gasses that are present
in air and
therefore are not likely due to the presence of the sealant but instead due
to exposure
to air.
A second series of tests was
performed on a solid piece of harden sealant.
An AC
hipot test
was performed on the square sample at increasing voltages.

The sample was
approximately 4” square and 1” thick.
Tests were performed corner to corner
and
front to back at test voltages up to 35000 Volts AC.
The material performed
a level of dielectric strength much greater than oil or air alone.
There is no indication
from the tests performed that the presence of this sealant will negatively
effect
the oil.
