When a new transformer is commissioned, establishing the Time Zero conditions is essential to start building the transformer’s analysis history. This package includes the key tests to run every time a new unit is put in place.
The recommended tests in this package include:
Dissolved Gas Analysis
Key gases detected: H2 (Hydrogen), O2 (Oxygen), N2 (Nitrogen), CH4 (Methane),
CO (Carbon Monoxide), CO2 (Carbon Dioxide), C2H4 (Ethylene), C2H6 (Ethane), C2H2 (Acetylene).
DGA as per ASTM D3612.
Water reduces the insulation capacity of the oil, excessive moisture accelerates
the decomposition of the paper insulation.
Moisture in Oil content test as per ASTM D1533.
Furanic compounds are produced as the paper insulation deteriorates;
measuring the concentration of those compounds gives an indication on the
condition of the paper insulation.
Furan content as per ASTM D5837.
Physical, Electrical and Chemical tests including: visual examination,
dielectric breakdown, acidity, interfacial tension, density and color.
All as per their specific ASTM test methods.
Oxidation occurs and inhibitor is consumed, controlling the inhibitor content
extends the life of the oil by preventing sludge formation.
Oxidation Inhibitor test as per ASTM D4768.
Power Factor 25°C and 100°C
Dissipation Factor is key for determining the presence of contaminants that cause
power losses in the oil.
Power Factor at 25°C and 100°C as per ASTM D924.
Polychlorinated Biphenyl content, Morgan Schaffer performs this analysis under
accreditation by the SCC. Results are recognized worldwide as being equivalent to
any accredited laboratory that is signatory to ILAC.
PCB analysis as per ASTM D4059.
