Short Circuit Current - Formula For

In AC systems, impedance (( Z )) is a vector combination of resistance (( R )) and reactance (( X )): ( Z = \sqrtR^2 + X^2 ). For high-voltage systems, reactance (primarily inductive) dominates.

[ I_sc,LG = \frac3 \cdot V_LNZ_1 + Z_2 + Z_0 ] formula for short circuit current

The feature should support two primary modes of calculation: In AC systems, impedance (( Z )) is

Isc=IFLCZ%÷100cap I sub s c end-sub equals the fraction with numerator cap I sub cap F cap L cap C end-sub and denominator cap Z % divided by 100 end-fraction Where (Full Load Current) for a 3-phase system is: In AC systems
