Figure 353:
Short circuit current waveform, fault occurs at time 0 seconds (Current
setting limit is multiplied by the square root of 2)
The phase voltage in a three-phase short circuit when a fault occurs at time = 0 s is shown
in
. The voltage drop caused by a three-phase fault provides more time for
determining the fault by means of an underimpedance protection.
