Webb2 nov. 2024 · The Importance of X/R Ratio. Specifically, circuits with a higher X/R ratio will have a longer time constant for the decay of the DC component, leading to a slower decay of the total current.

Webb18 apr. 2016 · Assuming Z1= Z0, this relation becomes 3Vth over 3V1, which is equal to the 3-phase short-circuit. But, if Z0< Z1, this implies If-t > I3p, that is, for phase-ground short-circuits near to the generator with a solidly grounded neutral, we do have If-t greater than I3p. That is the reason the generator designers put, at least, a small reactance ...
