Short Circuit Current Calculations - UNLV
– Find the Thevenin equivalent circuit looking from the fault point, then divide the Thevenin voltage by the Thevenin impedance. • You may use the Z-bus elements to determine the voltages and current flows elsewhere in the system (further away from the faulted bus) • Today, software tools to do the calculations for us are readily available.
