CoreSense TM  Hydrogen and Moisture Sensor   The sensor that enables Transformer Intelligence TM Transformer Service  Continuous online monitoring  CoreSense TM  provides real-time, continuous, online monitoring  of hydrogen and moisture levels in transformer oil. Hydrogen readings provide an early warning for most transformer faults; whereas moisture monitoring can prevent premature aging of a unit. Early detection of such incipient faults thereby allow you to take preemptive measures, when needed.  Hydrogen-specific sensor Unlike other products on the market that monitor a combination of gases dissolved in oil, CoreSense TM  is a hydrogen-specific  sensor. Hydrogen is the first indicator of most transformer faults and CoreSense TM  can alert the transformer owner to a possible  problem. A laboratory Dissolved Gas Analysis (DGA) will need to be performed after a serious alert in order to assess the root-cause of high gas levels in oil. Easy installation CoreSense TM  is easy to install and use. Thanks to its innovative  thermal element that induces convection currents by heating the oil, it can be connected to new or existing transformers, all types and brands, and at any location including the drain valve.  Maintenance free CoreSense TM  is designed for maintenance-free operation. This is  the result of heavy-duty, industrial grade design with no moving parts and a robust all-metal enclosure.– Industrial grade enclosure: IP67/NEMA 4X rating can operate    under one meter (3 feet) of water.– The Sensor is made of solid-state elements that do not drift    over time and are not consumables.– The thermal element eliminates any moving parts, such as a    mechanical pump that can be prone to failure. Simple interface – ABB can provide Transformer Intelligence TM  for a single       transformer, or an entire fleet, through a centralized dashboard  based on input from individual sensors. Collected data is    available for download in .csv format for offline analysis – Whether looking at the LED alarms on the device or at the      intuitive web interface, the message will be concise and simple    to read– WARNING and ALARM settings are user-configurable for both    hydrogen and moisture levels Variety of communication protocols – CoreSense TM  is equipped with multiple communication options     to suit varying needs. From classical 4-20 mA analog and digital    relay outputs to the latest fiber optic based Ethernet   connectivity, CoreSense™ has you covered.– Ability to connect to load and oil temperature sensors when      equipped with analog input Hydrogen in transformer oil, above all  other gases, is a key indicator of potential  transformer problems; resulting in  interrupted operations and unplanned  expenditures. Monitoring hydrogen  levels with CoreSense TM  is the most cost- effective, condition-based maintenance  approach to mitigate these risks, and to  ensure reliable transformer performance  and optimized maintenance planning.
