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

The procedure for transformer oil test results involves sampling the oil, conducting laboratory analyses, and interpreting the data. Key parameters evaluated include dielectric strength, moisture content, acidity, dissolved gas analysis (DGA), and furan analysis. These tests assess the oil’s insulating properties, contamination levels, and overall condition, helping to determine the transformer’s health and predict potential failures. Regular testing is essential for effective maintenance and reliability of power transformers.
