Introducing the CoreSense

The CoreSense continuously monitors hydrogen and moisture levels in oil and alerts the user when 
either one starts increasing beyond a predefined threshold. Real-time monitoring complements 
periodic off-line dissolved gas analysis (DGA) by alerting the user much sooner to evolving conditions.

The CoreSense can be mounted at multiple locations on the transformer including on the drain valve 
because it uses a heating element to induce forced convection and ensure that fresh representative oil 
is always reaching the solid state sensing elements.

The CoreSense user interface is designed as a series of simple web pages that can be accessed through 
most web browsers. The web interface allows viewing of the current CoreSense status and settings.
