* Period to be within the accuracy when the input changes from 0% to 100%f.s.
Averaging Method • Index averaging (applicable to 50 ms data update rate)
• Averaging is applied to voltage (U), current (I), and power (P), before perform-
ing calculations.
• For the harmonics, RMS values and percentage are calculated in average to
instantaneous values, and the phase angle is calculated in average of real part
and imaginary part after FFT calculation.
• Phase differences, distortion ratios and unbalance ratios are calculated from
the data averaged as above.
