3.4.1 Per-Cycle Accumulated Phase Voltage Quantities

The metrology module generates the following accumulated phase voltage (V²) quantities: CYCLE_V_A, CYCLE_V_B, CYCLE_V_C, CYCLE_V_A_F, CYCLE_V_B_F, and CYCLE_V_C_F.

They are in units of [Volt²samp scaled]. They are scaled accumulated phase voltage quantities in the last line cycle measurement period. They are calculated according to the following formula:

Where,

V_x_sample_i is i^th sampled phase voltage value of phase x in present cycle
x = [A, B, C]
N = The number of samples in the last line cycle measurement interval

They may be used to calculate the RMS value of phase voltage.

The CYCLE_V_x and CYCLE_V_x_F are stored in the uQ24.40 format.
