9.2 Statistics
9.2.1 Average values
The device makes it possible to determine average values based on the available measure-
ment data.
The average is generated for the following measurement values:
– Voltages: phase to phase U12, U23, U31
– Voltages: phase to neutral conductor U1, U2, U3
– Frequency
– Currents I1, I2, I3, IN
– Active power: consumption, supply
– Reactive power: consumption, supply
– Apparent power
The measurement values are divided into groups. These groups can be configured inde-
pendently of each other.
The following groups have been formed:
– Voltages
– Frequency
– Currents
– Power
– Predictions
For each average value, the minimum and maximum averages are always recorded and
displayed. The data can be called up via the web server, the display and via the communi-
cation interface.
There are three different types of average value generation:
– AVG over fixed interval
– AVG over rolling interval
– AVG over sliding interval
The average value types are described in the following sections.
The figures show the three different types of average value calculation. Select a time inter-
val that the measuring device will then use for calculating the average.
