What is the procedure for transformer oil testing laboratory and what parameters are evaluated?

The procedure for transformer oil testing in a laboratory typically involves sampling the oil, followed by a series of standardized tests. Key parameters evaluated include dielectric strength, moisture content, acidity, dissolved gas analysis (DGA), and furan analysis. These tests assess the oil’s insulating properties, chemical stability, and overall condition, ensuring the transformer operates efficiently and safely. Regular testing helps in predicting potential failures and maintaining transformer reliability.
