the resulting signal, together with the pre-processed and digitalized current signal
Equation 8:
i(t) = I
⋅ sin(ωt + ϕ)
See Figure 26: "Active energy computation diagram" (6)
are then available for the calculation process. These digital signals are also provided to two
additional stages, which then integrate of themselves, obtaining:
Equation 9:
dv/dt → v(t) = V
⋅ sin ωt
see below figure (7)]
Equation 10:
i(t) → I(t) ∫ i(t)
⋅ dt = = –I/ω ⋅ cos(wt + ϕ)
See figure below (8)
Figure 26: Active energy computation diagram
At this point four signals are available. By combining (pairing) them by means of two
multiplying stages, two results are obtained
