What is the testing process for transformer oil in power transformers as presented in the PPT?

The testing process for transformer oil in power transformers typically involves several key analyses. These include dielectric strength testing to assess insulation properties, moisture content analysis to determine water levels, and dissolved gas analysis (DGA) to identify potential faults. Additionally, tests for acidity, color, and flash point are conducted to evaluate the overall condition of the transformer oil. This comprehensive testing ensures the reliability and safety of power transformers.
