3.3.3 Accumulated Voltage Quantities Between Phases
The metrology module generates the following accumulated phase voltage (V) quantities between phases: V_AB, V_BC, V_CA, V_AB_F, V_BC_F and V_CA_F.
They are in units of [Volt2samp scaled]. They are scaled accumulated voltage quantities between phases 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; V_y_samplei is ith sampled phase voltage value of phase y in present integration period; x = [A, B, C]; y = [B, C, A]; N is the number of samples in the last measurement interval.
They are used to calculate the RMS value of voltage between phases.
V_xy and V_xy_F are stored in uQ24.40 format.
