6.6.48 Reactive Power 1 (Q1
Avg
) – Page 16, Address 14
Default = 0x00 0000
Reactive power 1 (Q1
AVG
) is Q1 averaged over each low-rate interval (SampleCount samples) and corrected
by Q
OFF
.
This is a two's complement value in the range of -1.0
value 1.0, with the binary point to the right of the MSB.
6.6.49 Instantaneous Quadrature Power 1 (Q1) – Page 16, Address 15
Default = 0x00 0000
Instantaneous quadrature power, Q1, the product of V1 shifted 90 degrees and I1.
This is a two's complement value in the range of -1.0
value 1.0, with the binary point to the right of the MSB.
6.6.50 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
value 1.0, with the binary point to the right of the MSB.
6.6.51 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
value 1.0, with the binary point to the right of the MSB.
