- Detect problems inside transformer (electric fault)
- Gives informaition about rate of aging (oil and paper(
- Varifay Oil Specification
Friday, October 30, 2015
-Provide the appropriate amount of maintenance at the right time.
- A majority of all transformer failure can be prevented.
- Oil analysis can be done during operation.
- majority of all the diagnostic information indicating the
condition of the transformer can be derived from oils.

• When a new transformer is in service, you should start building the
transformers analysis history.
The recommended tests :
•
•
•
Dissolved Gas Analysis
Water Content
ASTM Package
BDV, Visual aspect, Color, Acidity, IFT, Density
his basic package is the first step when trying to locate and identify specific
transformer problem, the result of these test will allow you to determine what
other test are required to be performed in order to have a clear understanding of
your transformer actual condition.

Universal accepted
method to locate
incipient Thermal and
Electrical fault
Friday, October 30, 2015
Fault gases are caused by corona (partial discharge), thermal heating
(pyrolysis) and arcing.
The Gas Concentrations in the oil depend upon :
The volume of oil involved
(dilution factors)
The age of the transformer
(new or old)
The type of transformer
(Generator or Transmission)
(Sealed or free breathing)
(Construction of Tap changer)

The core of transformer was found to be delaminate due to Corrosion caused
by high humidity (73ppm)
