As the saying goes, oil and water don’t mix, add to the idea that this insulating oil is charged with electricity. The effects can be catastrophic and definitely costly. The doblePRIME DOMINO™ provides real time data for moisture in oil, giving indications of relative saturation or absolute ppm levels. This is useful information, especially when a transformer is being loaded in excess of nameplate or when the transformer is undergoing abnormal load cycles. The doblePRIME DOMINO provides continuous reliable measurement of the water content of electrical insulating liquids and other types of oils.
