Short Circuit Current Calculation ❲CONFIRMED ✭❳

Q: How do I calculate the short circuit current? A: The short circuit current can be calculated by determining the Thevenin impedance of the power system, looking back from the fault location, and using the system voltage.

Isc=IflZpu=1202.810.0575≈20918.43 Acap I sub s c end-sub equals the fraction with numerator cap I sub f l end-sub and denominator cap Z sub p u end-sub end-fraction equals 1202.81 over 0.0575 end-fraction is approximately equal to 20918.43 A 4.

You must calculate both. Ignoring the ground fault is like building a tsunami wall but forgetting the back door is open. Q: How do I calculate the short circuit current
