Short Circuit Analysis Module
The short circuit module determines fault currents and impedances due to system faults. The results of the analysis include fault currents for all types of fault (phase-ground, phase-phase, 3-phase and phase-phase-ground) along with the Thevenin impedances of the faulted system.
The short circuit analysis gives results for maximum and minimum fault levels at each node included in the analysis. DESS allows you to specify both maximum and minimum source impedances when representing supplies from the transmission system and you can also choose whether to automatically exclude generation and motors when calculating minimum fault levels.
You can also choose to use values based on ANSI/IEEE C37 fault analysis or to use IEC 60909 correction factors when calculating fault values.
