x/R: X/R fault = (Xutil + X txmr) / (Rutil + Rtxmr )
pf: ratio of the real power flowing to the load, to the apparent power
FLA: Full load amperes
generator mode of operation:
swing: output power change based on load demand
voltage, Mvar control: output power fixed

TCC: In order to determine the proper setting for the Overcurrent protective devices they are plotted on
time-current curve graphs (TCCs). The time-current characteristics of properly coordinated devices will not overlap on a TCC graph.

thevenin equivalent:
Calculate the output voltage, VAB, when in open circuit condition (no load resistor—meaning infinite resistance). This is VTh.
Calculate the output current, IAB, when the output terminals are short circuited (load resistance is 0). RTh equals VTh divided by this IAB.
The equivalent circuit is a voltage source with voltage VTh in series with a resistance RTh.
