Short Circuit Current Calculations
... Normally, short circuit studies involve calculating a bolted 3-phase fault condition. This can be characterized as all 3-phases “bolted” together to create a zero impedance connection. This establishes a “worst case” (highest current) condition that results in maximum three phase thermal and mechani ...

This method prevents zero-crossings from dictating a single event or notch from impacting the amount of excitation by constantly pulsing and adjusting the duty cycle. The power input waveform is only used for excitation output and is filtered and rectified to a DC ...
