What information is included in a transformer oil test report format?

A transformer oil test report includes sample identification, sampling date, transformer details, test methods used, and measured values for parameters such as moisture, BDV, acidity, interfacial tension, DGA, and sometimes furan content. Results are compared with standard limits and previous trends. Interpretation comments and maintenance recommendations are often included. The report provides a documented basis for asset condition assessment, regulatory compliance, and maintenance decision making.
