Oil Materials Analysis

DOMINO

Doble developed one of the first analytical techniques for measuring dissolved water in oil, as well as the DOMINO Ultimate Sampling System (USS) and the Moisture-in-Oil (MIO) sensor. You can use these instruments to manage the state of your bushings/CTs, transformers, and circuit breakers.

DOMINO USS gives you a fast, convenient way to measure water content in oil while you’re performing other field tests. The MIO sensor is a simple, accurate, robust device that measures moisture in oil in terms of ppm and relative saturation, along with temperature. It allows continuous, reliable measurement of the water content of electrical insulating liquids and other types of oils.

Doble Laboratory

The Doble Laboratory is fully equipped to perform a wide variety of tests on insulating materials, with more than fifty tests offered on a routine basis. The Doble Laboratory can provide answers and solutions to your problems, based on quality data from a wide scope of testing capabilities and rich experience in apparatus diagnostics. We can help you develop the most cost-effective testing program for condition assessment or help identify and solve apparatus problems. All test reports include an analysis of the data and recommendations for remedial action, if warranted.
