If this information is not available, the user can select “Estimate X/R ratio” and the program will add a value based on accepted IEEE standard curves.

%X”dV Rated-voltage (saturated) direct-axis sub-transient reactance. It is used for first-cycle and

interrupting time calculations. %X’dV Rated-voltage (saturated) direct-axis transient reactance. It is used for time delayed currents in

relay applications. Xd Rated current unsaturated direct-axis steady state reactance. %X”2V Rated-voltage negative sequence reactance. It is used to calculate the X/R ratio and for

unbalance short circuit calculations. %X0 Zero sequence reactance. It is used in unbalanced short-circuit calculation, when dealing with
