3.3.2 Accumulated Phase Voltage Quantities
The metrology module generates the following accumulated phase voltage (V2) quantities: V_A, V_B, V_C, V_A_F, V_B_F and V_C_F.
They are in units of [Volt2samp scaled]. They are scaled accumulated phase voltage quantities in the whole integration period. They are calculated according to the following formula:
Where, V_x_samplei is ith sampled phase voltage value of phase x in present integration period; x = [A, B, C]; N is the number of samples in the last measurement interval.
They may be used to calculate the RMS value of phase voltage.
V_x and V_x_F are stored in uQ24.40 format.
