Abstract :
In this paper the rough set theory which has been developed to derive the features of various coarse data was applied to the discharge currents accompanied by tree developments. The original current data were calculated to make a set of condition attributes at some time points and a decision attribute was also derived. The discernibility matrices presented by Skowron in the rough set theory were applied to the time dependent set of condition attributes and decision attribute to predict its future time series
