Fault calculations using three terminal Thevenin’s equivalent circuit
International Journal of Electrical Power & Energy Systems, 2011 Abstract The aim of this paper is to present a systematic approach of calculating fault currents due to the switching of elements or fault impedances that involve two buses and ground. Traditionally, Thevenin’s equivalent circuits are made up of two terminals suitable for calculating the current into an element connected between both terminals of the
