What is the procedure for transformer oil test set and what parameters are evaluated?

The procedure for a transformer oil test set involves collecting a sample of the oil, ensuring it is free from contaminants, and then conducting various 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, which are critical for ensuring the reliable operation of power transformers.
