Abstract
A method to minimize human intervention during decision making processes while controlling an electrical power system by identifying an initiating element that cause a tripping of the transmission overhead lines and identifying potential future protection system failures that can initiate a cascading of tripping or total national blackout. A method of producing flashover analysis signal as a protection system analysis including processing a neutral current, three phase current profile, three phase voltage profile, and a plurality of digital signal of a transmission line using an artificial neural network to calculate pickup time, reset time, DEF confirmation time or total fault clearance time. A method of producing flashover analysis signal including as a flashover signature analysis to identify the cause of the flashover as a current transformer explosion, tree encroachment, crane, lightning strike or polluted insulator.
