The benefit of frequency tracking is that the measurements are within a pre-defined accuracy range even when the fundamental frequency of the power system changes. Frequency independent current and voltage measurement accuracy is achieved with algorithms specified in patent US 10,809,287. © Arcteq Relays Ltd IM00030...
Page 74 FFT calculation always has a whole power cycle in the buffer. The measurement accuracy is further improved by Arcteq's patented calibration algorithms that calibrate the analog channels against eight (8) system frequency points for both magnitude and angle.
