SIGNAL PROCESSING

L30 LINE CURRENT DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL

Figure 2-4: UR signal processing

The UR samples its AC signals at 64 samples per cycle, that is, at 3840 Hz in 60 Hz systems, and 3200 Hz in 50 Hz systems. 
The sampling rate is dynamically adjusted to the actual system frequency by an accurate and fast frequency tracking 
system.
The A/D converter has the following ranges of AC signals:
Voltages:

Eq. 2-1

Currents:

Eq. 2-2

Current harmonics are estimated based on raw samples with the use of the full-cycle Fourier filter. Harmonics 2nd through 
25th are estimated.
