Coulometric method is suitable for samples with low water content (10 μg ~ 100 mg)The volumetric method is suitable for samples with higher water content (0.1 to 500 mg).
The interfacial tension between oil and water reacts to the affinity between oil and water. If the tension is large, oil and water are not easily miscible (emulsified), and oil is easy to dehydrate during refining (an important indicator of insulating oil is that trace water PPM cannot exceed the st
