6.1.23 Fundamental Reactive Power Register ( Q
H
)
Address: 31 (read only)
Fundamental Reactive Power (Q
H
) is calculated by performing a discrete Fourier transform (DFT) at the relevant
frequency on the V and I channels. The value is represented in two's complement notation and in the range of
-1.0
 Q
H
 1.0, with the binary point to the right of the MSB.
