The Harmonic Active Power (P H ) is calculated by subtracting the Fundamental Active Power from the Active
(Real) Power. The value is represented in two's complement notation and in the range of -1.0 ? P H ? 1.0, with
the binary point to the right of the MSB.

The Fundamental Active Power (P F ) is calculated by performing a discrete Fourier transform (DFT) at the rele-
vant frequency on the V and I channels. The results are multiplied to yield fundamental power. The value is rep-
resented in two's complement notation and in the range of -1.0 ? P H ? 1.0, with the binary point to the right of
the MSB.
