The values determined and calculated using the function "Dissolved gas
analysis" can exhibit measuring inaccuracies that arise from the measuring
inaccuracies of the sensors. Therefore, refer to the sensor operating instruc-
tions for further information on the measuring accuracy and any necessary
calibration.
Depending on the device configuration, the dissolved gas analysis includes
the following sub-functions:
▪ Display of the absolute values
▪ Display of the rates of increase
▪ Display of the measured value trend
▪ Additional, as an option:
– Duval analysis
– Rogers analysis
– Dörnenburg analysis
– IEC 60599 analysis
7.14.1 Configuring DGA monitoring
For the DGA monitoring "DGA", you can set 3 limit values for the absolute
values and for the rates of increase. Depending on the device configuration,
you can monitor up to 11 DGA signals. You can also set the following pa-
rameters:
▪ Sensor measuring accuracy
▪ Reset diagnostic errors
▪ Rates of increase evaluation interval
▪ Relative moisture in oil default value
▪ Use relative moisture in oil default value
