What is the process for transformer oil analysis in power transformers?

The process for transformer oil analysis in power transformers involves several key steps. First, a sample of the transformer oil is collected under controlled conditions to avoid contamination. Next, laboratory tests are conducted, including dissolved gas analysis (DGA), moisture content measurement, and furan analysis. These tests help identify the presence of gases, moisture, and degradation products, providing insights into the condition of the transformer and potential issues that may affect its performance and reliability.
