"The object of this thesis is to present a method for the analytic determination of fault currents and voltages of a symmetrical three-phase system that is subjected to three simultaneous faults. The fault analysis is to be effected by the method of symmetrical components...Though relatively infrequent, simultaneous faults are important because relay systems, operating satisfactorily for single faults, may fail to isolate simultaneous faults. Therefore, it seems worthwhile to have in convenient form a method for calculating short-circuit currents and voltages caused by faults occurring at the same time at three separate and distinct points of a system. It is the purpose of this paper to outline this method in detail, developing the equations and constants necessary for a ready calculable solution"--Introduction, page 1-2.
