Operation principle
The sampled analogue phase currents are pre-processed in a discrete Fourier filter
(DFT) block. The RMS value of each phase current is derived from the fundamental
frequency components, as well as sampled values of each phase current. These phase
current values are fed to the instantaneous phase overcurrent protection 3-phase
