cooler. For that purpose, there are many conditions of it, those conditions are
purity, density, kinematic viscosity, flash point, pour point, neutralization number,
corrosive sulphur, breakdown voltage, dielectric dissipation factor, oxidation
stability, water contents, resistivity, interfacial tension, gas contents. Standard of
the oil transformer test is using SPLN, which SPLN standard based on D3C
(International Electrotechnical Commission), ASTM (American Standard
Technical Measurement), ISO (International Standard Organization).
Quality of oil transformer will be decrease after usage, which reduce the
capability, strength, and the age. So that, checking of the oil transformer would
be necessary, at least once a year and checked to the laboratory.
In this final assignment discussion of testing and maintenance oil
transformer on PLN laboratory, usually are breakdown voltage, flash point,
neutralization number, dielectric dissipation factor, water contents, resistivity,
interfacial tension, sedimentation, gas contents. Treatment of the secondhand oil
transformer with regeneration process. That can described with screening for the
sludge and vacuum the gas contaminator and water contents.
When the parameter of oil transformer in testing process still in permitted
condition, the oil can use, unless oil needs treatment and refining.
