Online gas-in-oil measurement sensor Hydrocal 1004 genX, a system with 4 outputs for measuring:
- H2 Hydrogen
- CO Carbon monoxide
- C2H2 Acetylene
- H2O Moisture
Hydrocal 1004 genX
The new HYDROCAL 1004 genX is the first maintenance-free multi-gas online DGA solution combining proven near-infrared (NIR) measuring technology with vacuum-protected membrane extraction.
As Hydrogen (H2) is involved in nearly every fault of the insulation system of power transformers and Carbon Monoxide (CO) is a sign of involvement of the cellulosic / paper isolation, the presence and increase of Acetylene (C2H2) classifies the fault as overheating, partial discharge or high energy arcing.
Key Advantages
- Individual measurement of Hydrogen (H2), Carbon Monoxide (CO) and Acetylene (C2H2)
- Moisture in Oil (H2O) measurement
- Easy to mount on a transformer valve (G 1½" DIN ISO 228-1 or 1½" NPT ANSI B 1.20.1)
- Easy to mount on the operating transformer without any operational interruption
- Maintenance-free system due to less movable parts
- Advanced software (on the unit and via PC) with intuitive operation by 7” colour TFT capacitive touchscreen, WLAN and Web server operation from any smartphone, tablet or notebook PC
- Communication interfaces ETHERNET 10/100 Mbit/s (copper-wired / RJ 45 or fibre-optical / SC Duplex) and RS 485 to support MODBUS® RTU/ASCII, MODBUSÒTCP, DNP3, proprietary communication protocols and substation communication protocol IEC 61850
- Optional external I/O module
Communication
