TXpert™ Ready DGA Sensor CoreSense™

Hitachi Energy's CoreSense gives continuous online monitoring of transformer gases, such as hydrogen and moisture. CoreSense™ is qualified as TXpert Ready Sensor to connect with CoreTec 4, the TXpert Hub, that monitors hydrogen levels in transformer oil to provide an early warning for most incipient transformer faults and complement traditional offline laboratory Dissolved Gas Analysis (DGA) of the transformer oil.

Easy installation

Hitachi Energy's CoreSense™ can be installed on any transformer brand and type, old as well as new, or on a whole fleet of transformers. Thanks to CoreSense™ innovative thermal pump design that uses no moving parts, CoreSense™ can be connected to the transformer at any location, including the drain valve.

Universal fluid support

Hitachi Energy's CoreSense™ can be used with transformers filled with the following fluids:

  • CoreSense™ ST for mineral oils
  • CoreSense™ SE for synthetic ester (Midel 7131)
  • CoreSense™ NE for natural ester (Cargil FR3)
  • CoreSense™ SL for silicon fluids

Low maintenance
