6.6.54 Reactive Power 2 (Q2
Avg
) – Page 16, Address 16
Default = 0x00 0000
Reactive power 2 (Q2
AVG
) is Q2 averaged over each low-rate interval (SampleCount samples).
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.55 Instantaneous Quadrature Power 2 (Q2) – Page 16, Address 17
Default = 0x00 0000
Instantaneous quadrature power, Q2, the product of V2 shifted 90 degrees and I2.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.56 Peak Current 1 (I1
PEAK
) – Page 0, Address 37
Default = 0x00 0000
Peak Current 1 (I1
PEAK
) contains the value of the instantaneous current 1 sample with the greatest magnitude
detected during the last low-rate interval.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.57 Peak Voltage 1 (V1
PEAK
) – Page 0, Address 36
Default = 0x00 0000
Peak voltage 1 (V1
PEAK
) contains the value of the instantaneous voltage 1 sample with the greatest magni-
tude detected during the last low-rate interval.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.58 Apparent Power 1 (S1) – Page 16, Address 20
Default = 0x00 0000
Apparent power 1 (S1) is the product of V1
RMS
and I1
RMS
or SQRT(P1
AVG
2
+ Q1
AVG
2
).
This is an unsigned value in the range of 0
value 1.0, with the binary point to the right of the MSB.
