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

The procedure for a transformer oil test report involves sampling the oil, followed by laboratory analysis. Key parameters evaluated include dielectric strength, moisture content, acidity, dissolved gas analysis (DGA), and furan analysis. These tests assess the oil’s insulation properties, contamination levels, and overall condition, ensuring the transformer’s reliability and performance. The results are documented in a report, providing insights into the health of the transformer and necessary maintenance actions.
