What is the analysis of oil used in transformers?

The analysis of oil used in transformers involves several key tests to assess its quality and performance. These tests include measuring the dielectric strength, moisture content, acidity, and dissolved gas analysis (DGA). The analysis of oil helps identify potential issues such as insulation degradation, overheating, and the presence of contaminants, ensuring the reliable operation of power transformers and preventing failures. Regular analysis is crucial for maintenance and operational efficiency.
