Does your transformer have a water problem that you do not know about?
Now there is a better way to know the condition of important transformers than a once a year Karl Fischer Titration for water...DOMINO

Doble's Moisture-in-Oil Sensor, DOMINO:

• Provides instantaneous results in parts per million (ppm)
• Effectively monitors oil reconditioning, such as when to change filters, or to stop the process
• Continuous measurement allows for estimation of the moisture content of the transformer insulation system and hazardous conditions, which may occur during temperature cycling, helping prevent transformer failures
• Can be used to estimate the water content of the paper insulation
• Provides measurement of the relative saturation of water and temperature of the oil
• The sensor operates directly in the oil so it can be installed directly into the transformer or processing equipment
• Very compact in size
• Extremely versatile
