Removal of decaying DC in current and voltage signals using a modified Fourier filter algorithm.

Protecting transmission lines frequently involves applying distance relays. Protective relays must filter their inputs to reject unwanted quantities and retain signal quantities of relevant interest. Accuracy and convergent speed of filter algorithm are essential for protective relays. A widely appl...
