Need of Transformer Oil Testing

Power transformers are containtg oil which is highly-refined mineral oil. Due to its stablity in high temperature and excellent electrical insulating properties, It is use in high voltage electrical instruments.Presence of oil in transformers is important to keep it cool. Its also provide electrical insulation for internal part of transformers.

For Transformer's better performance it is important , that the oil should remain pure. Every Company having Power Transformer should go for Transformer oil testing at least once in a year. Oil analysis and testing helps to work your transformer well and also it is important to detect other problems in Transformers.

Main reason of Transformer oil testing is to evaluate the purity of Oil. This test includes 9 parameters according to IS method. These are

Transformer Oil Testing according to IS:1866

1. Electric Strength (BDV)
2. Water Content (PPM)
3. Tan Delta
4. Resistivity
   
5. Acidity
   
6. Sludge
7. Flash Point
8. Interfacial Tension

Transformer Oil Testing according to IS:10593

• Dissolved Gas Analysis (DGA)

As regular health check up can help you to stay healthy in the same way Transformer also needs regular check up to work well.

A company should always get its Transformer testing through an authorize testing lab. With better testing equipments and qualified testers you can get relevant and accurate results.
