Abstract

Five single-phase short-circuit tests were performed on the live 735-kV system. Transient currents and voltages were recorded on magnetic tape. The transmission system under fault conditions was simulated on a digital computer. The measured and simulated transients were superimposed on the same graphs using a computer-controlled plotter. The accuracy of measurements was evaluated and the graphs of the simulated transients were compared with those of the measured ones. This comparative study was then used for an experimental check of the computer simulation and provided reassurance that the system modeling was precise enough for further transient analyses.
