GE HYDRAN M2 | Integrated Transformer Monitoring Device

GE HYDRAN M2 is an economical and powerful integrated transformer monitoring device, based on on-site verification technology and added with IEEE based technology ® 

And IEC ® The standard transformer mathematical model can monitor the fault gases and humidity in transformer oil in real time, and can also monitor more forms of transformer faults.

· Measurement range: The gas measurement range is 0-2000ppm (equivalent volume of hydrogen gas (H ₂)/volume).

· Measurement accuracy: Gas reading is ± 10%, ± 25% ppm (equivalent amount of hydrogen); Hydrogen (H ₂) accounts for 100% of the content; Carbon monoxide (CO) accounts for 18 ± 3% of the content; Acetylene (C ₂ H ₂) accounts for 8 ± 2% of the content; Ethylene (C ₂ H ₄) accounts for 1.5 ± 0.5% of the content.

· Humidity measurement: It can provide humidity display in RH% and ppm formats.

· Functional features: It has full system self-test and self diagnostic functions; Digital display with flip screen control; There are 4 programmable relays for alarm purposes; 4 

expansion I/O plug connectors, capable of connecting isolated 4-20mA analog input cards, isolated dual channel digital input cards, and isolated 4-20mA analog output cards; 

1 communication expansion plug connector, can be connected to Ethernet 10-100Base T card or analog modem; Support DNP3 protocol (serial interface or TCP/IP); Expanded 

adjustable frequency data and event logs; Adjustable alarm settings based on levels and trends for gas, humidity, analog inputs, and transformer model calculations; A friendly 

client/server graphical user interface (GUI) that allows multiple clients to access through TCP/IP.
