®
DGA 2/3
Detailed information on using the MESSKO®MSET parameterization soft-
ware can be found in the corresponding operating instructions.
7.3 Commissioning in existing systems
The manufacturer recommends a field calibration of the device parameters
to ensure optimum operation, in particular with:
▪ Aged insulating oils
▪ Modified oils (e.g., the addition of additives)
▪ Oils that do not satisfy the standards ASTMD3486-091, IEC60296 or
IEC60422.
Here, an oil sample must be taken in accordance with the chapter "Oil ex-
traction" [►Section 10.3, Page 69] and sent to Messko GmbH together with
the "SAMPLE DATA SHEET – OIL ANALYSIS". You will then receive a rec-
ommendation for action from Messko for readjustment via the MESSKO®
MSET parameterization software.
7.4 Parameterization
Parameterization of the device is only possible in combination with the
MESSKO® MSET parameterization software, and is described in detail in
the corresponding operating instructions.
The set values for the gas carbon monoxide (CO) are only available for the
device version MSENSE® DGA 3.
The following settings can be configured for the parameters CO, H2
and H2O (as relative or absolute):
▪ Concentration warning limit
▪ Concentration alarm limit
▪ Gas formation rate warning limit
▪ Gas formation rate alarm limit
▪ Value for 4mA signal
▪ Value for 20mA signal
▪ Concentration action warning limit
▪ Concentration action alarm limit
▪ Gas formation rate action warning limit
▪ Gas formation rate action alarm limit
Further settings
▪ H2O reference
▪ Measurement interval
▪ Time stamp
