For the radial distribution system shown in the figure below, the impedances of the two line sections and the equivalent generator are given in pu. Consider symmetrical faults only (three-phase, positive sequence) and assume that the relay at bus A is set to pickup for a fault at bus C. The relay at bus B is set to pickup at one half of that value. 2) Assume there is a DER installed at bus C whose fault current contribution is...
