Datasheet

MTE HYDROCAL 1001+ Online Composite Dissolved Gas Analysis & Moisture

Description

The HYDROCAL 1001+ is a permanently installed composite gas-in-oil sensor for the analysis of the following dissolved key fault gases (TDCG = Total Dissolved Combustible Gases):

Fault Gas TDCG Contribution
Hydrogen (H2) approx. 20 %
Carbon Monoxide (CO) approx. 30 %
Methane (CH4) < 5 %
Acetylene (C2H2) 100 %
Ethylene (C2H4) approx. 32 %
Ethane (C2H6) < 5 %

To provide an even more comprehensive transformer monitoring solution, the HYDROCAL 1001+ analyses additionally the content of moisture (H2O) in the transformer oil.

The integration of 6 relevant key gases into a total weighted gas concentration and the measurement of Moisture in oil enables the HYDROCAL 1001+ to react to most transformer faults and makes the device to a compact and cost-effective tool used for early transformer fault detection and preventative maintenance.

Key advantages:

  • Composite measurement of Hydrogen (H2), Carbon Monoxide (CO), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4), Ethane (C2H6) and dissolved Moisture (H2O) in the transformer oil
  • Relay outputs with light indicators showing potential alerts
  • Easy and fast installation without any operational interruption of the transformer
  • Compact and resistant design for long lasting usage
  • Communication interfaces ETHERNET 10/100Mbit/s (copperwired or fibre-optical) and CAN bus to support proprietary communication protocols and to be prepared for sub-station communication protocols MODBUS®TCP and CANopen
