Parameters
13.2 Description of parameters
Minimum and maximum value calculation
Enable calculation of the minimum and maximum values. The minimum and maximum value
are calculated from the start of the measurement. The values determined are stored
retentively in the AI Energy Meter HF together with the time stamp.
Minimum and maximum value calculation gate
Enable the gate for minimum and maximum value calculation. When the gate is enabled, the
energy meter only counts when the corresponding output data bit (DQ bit) is set to "1".
Power quality analysis function
Enable the power quality analysis function for the entire module.
Residual current analysis
Enable the residual current analysis for the entire module. The residual current analysis is
only available in the connection types 3P4W or 3P4WI and the concurrently activated
parameter "Neutral current measurement".
Neutral current measurement
Defines whether the neutral current is measured or calculated.
This parameter does not apply to parameter assignment with GSD file.
Neutral: Current transformer primary current [A]
To determine the current transformer ratio, enter the primary current. The transformer ratio is
calculated from the primary and secondary current.
The following applies to parameter assignment with GSD file:
● 0 = Neutral function deactivated
● 1 ... 99999 = measure neutral current
● 4294967295 = calculate neutral current
Neutral: Current transformer secondary current [A]
To determine the current transformer ratio, enter the secondary current. The transformer
ratio is calculated from the primary and secondary current.
Voltage dip limit value in relation to nominal value voltage [0.1%]
Further information can be found under Voltage dip of the voltage half-wave value
(Page 118).
