: Determine resistance and reactance based on material, length, and cross-sectional area. Sum the impedances : Add all resistances ( ) and reactances ( Solve for Isccap I sub s c end-sub : Apply Ohm's Law. Method B: The Per-Unit (PU) Method
What runs down to the fault point?
Using the per unit system and Thevenin's theorem, the short circuit current at the generator terminal can be calculated as follows: short circuit current calculation
IEEE Std 141 (Red Book) and IEC 60909 recognize three main types of faults (with a fourth common variant): : Determine resistance and reactance based on material,
