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

The Fundamental Active Power (P ) is calculated by performing a discrete Fourier transform (DFT) at the rele-
F
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 < 1.0, with the binary point to the right of
H
the MSB.
