А Hi DVR 5 MW load Unity PF Fault Problem 4 Part of a distribution network is shown. The impedance of the feeders are ZAB = 2+j6 and ZBC = 1+j5 2. Assume before the fault, voltage at busbar D is 120. pu. Consider the bases of 10 MVA and 13.8 kv. a) Calculate the voltage at the load bus when a fault occurs at bus B with a fault impedance of ZFault=j10 . b) Calculate the magnitude of the DVR voltage that should be injected to maintain the voltage at bus D as 120. pu.
