It is recommended to perform routine tests at least once a year in order to monitor the health of your transformers. Faults can occur at any stage of your transformer's life and evolve rapidly. Testing your transformers on a regular basis will allow you to detect any unforeseen change in the condition of your transformers.
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.
