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.
The HYDROCAL 1001+ is equipped with 2 Analogue 0/4 … 20 mA outputs for the dissolved composite gas-in-oil and moisture in oil analysis results and 4 digital relay outputs (Hi-alarm, Hi-Hi-alarm, moisture-alarm and system function alarm).
