Introduction to Short Circuit Current Calculations
... For electrical systems where any or more of the above conditions exist, it is advisable to perform a single line-to-ground fault simulation. Line-to-line or double line-to-ground fault studies may also be required for protective device coordination requirements. Also, since only one phase of the lin ...
