- The duration of voltage sag caused by fault is depended on the fault clearing time of the protection system. In traditional assessments on voltage sag are simply assumed that the duration obeys some distribution of random or is a constant value. In order to depict the duration of voltage sags more precisely, time characteristic of stepped current protection and protection scope of instantaneous current protection are taken into consideration, the two demarcation points of the protection operation on line are determined, the protection operation time of every segment is analyzed. An example is simulated by PSCAD/EMTDC software, and it is shown that more reasonable assessment is obtained by precise duration of voltage sag.
