6.6.37 Instantaneous Quadrature Power (Q) – Page 16, Address 15
Default = 0x00 0000
Instantaneous quadrature power, Q, the product of V shifted 90° and I.
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.
6.6.38 Peak Current (I
PEAK
) – Page 0, Address 37
Default = 0x00 0000
Peak current (I
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
value 1.0, with the binary point to the right of the
MSB.
6.6.39 Peak Voltage (V
PEAK
) – Page 0, Address 36
Default = 0x00 0000
Peak voltage (V
PEAK
) contains the value of the instantaneous voltage 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
value 1.0, with the binary point to the right of the
MSB.
6.6.40 Apparent Power (S) – Page 16, Address 20
Default = 0x00 0000
Apparent power 1 (S) is the product of V
RMS
and I
RMS
or SQRT(P
AVG
2
+ Q
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.
