Removal of Decaying DC Offset in Current Signals for Power System Phasor Estimation
This paper presents a new method for the removal of decaying de offset from current signals in digital protective devices. The method is based on the fact that a purely sinusoidal signal has a zero average over a full cycle or multiples of the full cycle of its fundamental frequency, whereas an expo...
