22.20.1 RMS values
The monitors calculate RMS values of "averaged over a second" quantities in the four quadrants. These
averages are as follows:
•
V
1
[avg], V2[avg], V3[avg]
•
U12[avg], U23[avg], U31[avg]
•
I1[avg], I2[avg], I3[avg], IN[avg]
The averages listed above are calculated from the following formula:
•
22.20.2 Arithmetic averages (A)
The monitors calculate arithmetic average values of the "averaged over a second" quantities in the four
quadrants. These average values are as follows:
•
S1[avg], S2[avg], S3[avg], S[avg]
•
F[avg], Des[avg]
•
THDV1[avg], THDV2[avg], THDV3[avg]
•
THDU12[avg], THDU23[avg], THDU31[avg]
•
THDI1[avg], THDI2[avg], THDI3[avg]
•
FCV1[avg], FCV2[avg], FCV3[avg]
•
FCI1[avg], FCI2[avg], FCI3[avg]
The averages listed above are calculated from the following formula:
•
22.20.3 Arithmetic averages (B)
The monitors calculate arithmetic average values of the "averaged over a second" quantities in the two
quadrants in receiver mode. These average values are as follows:
•
P
1
R[avg], P2R[avg], P3R[avg], PR[avg]
•
Q1R[avg], Q2R[avg], Q3R[avg], QR[avg]
If P
x
[1s] is positive or zero (receiver mode) it is the "averaged over a second" measured value which is
included in the average. When P
x
[1s] is negative (generator mode) it is set to 0, which is reflected in the
average.
22.20.4 Arithmetic averages (C)
The monitors calculate arithmetic average values of the "averaged over a second" quantities in the two
quadrants in receiver mode. These average values are as follows:
•
FP1R[avg], FP2R[avg], FP3R[avg], FPR[avg]
•
cos(

If P
x
[1s] is positive or zero (receiver mode) it is the "averaged over a second" measured value which is
included in the average. When P
x
[1s] is negative (generator mode) it is set to 1, which is reflected in the
average.
22.20.5 Arithmetic averages (D)
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:
