What is the process for conducting a moisture analysis of transformer oil?

The process for conducting a moisture analysis of transformer oil typically involves sampling the oil and using techniques such as Karl Fischer titration or capacitive sensors. In Karl Fischer titration, a reagent reacts with water in the oil, allowing for precise quantification of moisture content. Capacitive sensors measure the dielectric constant changes in the oil, correlating to moisture levels. Both methods ensure accurate assessment of moisture in transformer oil, which is critical for maintaining transformer performance and longevity.
