This 3-hour interactive online course reviews the principles of electric systems during faulted conditions and how short circuit currents are calculated in both three-phase and single-phase systems. Since short circuits have such damaging impacts on an electric system, the magnitude of the expected faults currents and their impact on the components in the circuit must be understood. The simplified analytical procedures presented in this course will allow the user to quickly determine the expected level of fault currents in an electric system. These procedures are generally considered adequate for most applications of 600-volts or less.
