TXpert™ Ready multi-gas DGA analyzer CoreSense™ M10

Hitachi Energy's CoreSense^TM M10 provides real-time, continuous, online monitoring of dissolved gas and moisture levels in transformer oil. The CoreSense^TM M10 is qualified as TXpert^TM Ready Sensors to connect with CoreTec^TM 4, the TXpert^TM Hub, which accurately measures the following nine gases in transformer mineral oils, ester, and silicon fluids.

• hydrogen 
• methane 
• acetylene 
• ethylene, 
• ethane
• carbon monoxide
• carbon dioxide
• propane
• propene 

Dissolved gas readings are used to provide early identification and warnings for most transformer faults, whereas moisture monitoring can prevent premature aging of a unit. Early identification and detection of such incipient faults thereby allow you to take preemptive measures when needed and avoid expensive outages.

Hitachi Energy's CoreSense^TM M10 minimizes the risks of oil leaks and simplifies the installation by using a single flange and limiting oil circulation to the sample head.

Hitachi Energy's CoreSense^TM M10 is designed for operation with no consumables. Thanks to its field-proven Fourier Transform Infrared spectrometer (FTIR) and industrial-grade design, the CoreSense^TM M10 will not drift over time and does not require any carrier or calibration gases. It reduces the risks of oil leaks with a simple pump-less oil circuit limited to the measuring head and uses built-in redundancies for reliable, maintenance-free operation.

Hitachi Energy's CoreSense^TM M10 can survive in harsh outdoor conditions with temperature extremes from -50°C to +55°C and corrosive conditions and can operate under one meter (3 feet) of water.

Hitachi Energy's CoreSense M10 can be used with transformers filled with the following fluids:

• CoreSense^TM M10 ST for mineral oils
• CoreSense^TM M10 SE for synthetic ester (Midel 7131)
• CoreSense^TM M10 NE for natural ester (Cargil FR3)
• CoreSense^TM M10 SL for silicon fluids
