I ask this question because I want to know how the ETAP software calculate the short circuit with method

Thanks

RE: Short circuit calculation
"In ANSI/IEEE short circuit calculations, an equivalent voltage source at the fault location, which equals the prefault voltage at the location, replaces all external voltage sources and machine internal voltage sources."
"In IEC short circuit calculations, an equivalent voltage source at the fault location replaces all voltage sources. A voltage factor c is applied to adjust the value of the equivalent voltage source for minimum and maximum current calculations."
There are many other differences; the complete details are explained in the ETAP Help section. Look at Chapter 15 - Short-Circuit Analysis; Calculation Methods.

If you want to choose between one of the two, I would agree with Mike's last comment: "where are you?"
