Transformer Oil Lab Testing & Diagnostics

Transformer Oil over time is exposed to Electrical, Chemical & Mechanical stress which causes contamination in oil. When the desired oil properties are reduced it can lead to power outages. So to maintain & extend the life of the Transformer Asset and to avoid severe breakdown, regular testing of the transformer oil is very important.

The transformer oil testing is done under the guideliens of IS 1866. The following test are conducted :

• Electric Strength (Break Down Voltage).
• Water Content (PPM).
• Tan Delta/ Dielectric Dissipation Factor.
• Resistivity.
• Total Acidity.
• Inter Facial Tension (IFT).
• Sludge Content.
• Dissolved Gas Analysis (DGA).
• Color & Appearance.
• Pour Point.
• Density.
• Kinematic Analysis.
• Furan Analysis.

We provide On-Site Oil Sample Collection Service. Just as a blood test provides a medical doctor with a extensive information about the patients health, similarly a sample of transformer oil, if taken correctly, can tell the transformer doctors a great deal about the transformer's condition. AEIL Sampling team have been trained in the strict routines needed to obtain a clean sample in accordance to IS 1866 .

The General & Physical tests are suggested to be conducted twice a Year, dissolved gas analysis testing once a year, and Furan analysis testing every 2 years for transformers which have been in operation for at least 5 years. Contact AEIL to know your Transformer's health through transformer oil analysis.
