6.6.48 Reactive Power 1 (Q1Avg ) – Page 16, Address 14

Default = 0x00 0000

Reactive power 1 (Q1AVG) is Q1 averaged over each low-rate interval (SampleCount samples) and corrected

by QOFF.

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 (Q2Avg ) – Page 16, Address 16

Default = 0x00 0000

Reactive power 2 (Q2AVG) 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.
