HYDROCAL 1011

The new HYDROCAL 1011 genX is the first truly maintenance-free multigas
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 an involvement of
the cellulosic / paper isolation the presence and increase of Acetylene
(C2H2) further classifies the nature of a fault as overheating, partial discharge
or high energy arcing.
The additional measurement of Ethylene (C2H4) and Methane (CH4)
serves for further analysis, e.g. Duval triangle according IEC 60599.
Key Advantages
• Individual measurement of Hydrogen (H2), Carbon Dioxide (CO2),
Carbon Monoxide (CO), Acetylene (C2H2), Methane (CH4) and Ethylene
(C2H4), Ethane (C2H6), Moisture in Oil (H2O), Propane (C3H8), Oxygen
(O2), Nitrojen (N2)
• 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” color TFT capacitive touchscreen, WLAN and Webserver
operation from any smart phone, tablet or notebook PC
• Communication interfaces ETHERNET 10/100 Mbit/s (copperwired
/ RJ 45 or fibre-optical / SC Duplex) and RS 485 to support
MODBUS® RTU/ASCII, MODBUSTCP, DNP3, proprietary
communication protocols and substation communication
protocol IEC 61850
Optional external I/O module
