Abstract
A method and an apparatus for dynamic signal switching with multiple measurement sources, for a merging unit in an electrical power system, said merging unit receiving at least two input signals from at least one current transformer measuring the same physical primary quantity. The method comprises a step of outputting from said merging unit, in a real-time mode, a digitized output stream of sampled values with the truest representation of the physical primary quantity, based on the actual values of the input signals.
