The paper deals with the chosen problems of short-circuit states identification which were included in the papers and presented at the International Symposia "Short-circuit Currents in Power Systems" in the years 1990-1998. The papers concern mainly filtering the fundamental component of short-circuit currents and voltages and estimation of amplitude of those signals. The method and algorithms used as well as the obtained results have been discussed.
