Hydrocal 1003

Maintenance free system

· Easy to mount on the operating transformer without any operational interruption

· ETHERNET (Option), RS 232 and RS 485 interfaces to support MODBUS® RTU/ASCII, DNP3 and proprietary communication protocols and to be open / prepared for substation communication protocol IEC 61850

· Option: Offshore version The Hydrocal 1003 is an online transformer monitoring device for the dissolved gas analysis (DGA) of the key fault gases Hydrogen (H2) and Carbon Monoxide (CO).

In addition, water contamination deteriorates the performance of the oil as high moisture content increases the risk of corrosion and overheating.

The Hydrocal 1003 reacts on this issue and provides its users the analysis of Moisture (H2O) in the transformer oil to achieve an even higher safety standard.
