If P
x
[1s] is negative or 0 (generator mode) it is the "averaged over a second" measured value which is
included in the average. When P
x
[1s] is positive or 0 (receiver mode) it is set to 0, which is reflected in
the average.
22.20.6 Arithmetic averages (E)
The monitors calculate arithmetic average values of the "averaged over a second" quantities in the two
quadrants in generator mode. These average values are as follows:
•
FP

G[avg], FP2G[avg], FP3G[avg], FPG[avg]
•

If P
x
[1s] is negative (generator mode) it is the "averaged over a second" measured value which is
included in the average. When P
x
[1s] is positive or 0 (receiver mode) it is set to 1, which is reflected in
the average.
22.21 Calculation of minima
Each minimum is time-stamped (date and time the minimum is detected). All minima can be reset by
writing a control word via remote or local communication. Resetting consists of setting the value of the
quantity to 0, with the exception of the minima of quantities of the type FP
x
and cos (
ϕ
x
), which are reset
to a value of 1.
22.22 Quantity minima
22.22.1 Minima (A)
The monitors calculate minima of the "averaged over a second" quantities in the four quadrants. These
minima are as follows:
•
V
1
[min], V2[min], V3[min]
•
U12[min], U23[min], U31[min]
•
I1[min], I2[min], I3[min], IN[min]
•
F[min]
The minima listed above are calculated from the following algorithm:

22.22.2 Minima (B)
The monitors also calculate minima of the "averaged over a second" quantities in the two quadrants in
receiver mode. These minima are as follows:
•
P

R[min], P3R[min], PR[min]
