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

The process for transformer oil testing in power transformers typically involves several key steps. First, a sample of the transformer oil is collected under controlled conditions to avoid contamination. Next, various tests are conducted, including dielectric strength, moisture content, and dissolved gas analysis. These tests help assess the oil’s insulation properties and overall condition, ensuring the reliability and safety of the power transformer. Regular testing is crucial for maintenance and performance monitoring.
