SubSafe Hydrogen Monitor | Monitoring Hydrogen in Transformers

SubSafe Hydrogen Monitor

Subsafe Hydrogen Monitor

Due to the tendency of hydrogen to be produced through a wide range of thermal conditions, online hydrogen monitoring is highly reliable as an early indicator of various internal transformer conditions ranging from partial discharge to the presence of active arcing. While historically measurements of hydrogen dissolved in oil has been the most common single gas method used for detecting these conditions, Dynamic Ratings’ SubSafe monitor measures hydrogen collected in the headspace of nitrogen blanketed transformers, taking advantage of hydrogen’s low solubility rates and higher in gas concentrations, to provide more consistent and reliable warnings as to the potential presence of incipient faults.

Maintenance Free Monitoring of Hydrogen Gas and Pressure

The SubSafe monitors hydrogen gas and pressure the headspace of the transformer, providing a more reliable indication to the development of abnormal operating conditions and changes in pressure of the main tank. The SubSafe monitor is maintenance free and self-calibrating.
