Power and energy calculation
The three-phase power is calculated from the phase-to-earth voltages and currents.
The power measurement function is capable of calculating a complex power based on
the fundamental frequency component (DFT).
Once the complex apparent power is calculated, P, Q, S and pf are calculated using
equations.
