Voltage dip trigger level and reset
level correspond to the settings of un-
dervoltage trip level and reset level .
Standard mode
Under standard mode, the reaction of the auto
restart function depends on the length of the volt-
age dip. Three scenarios (cases) are considered,
Case 1: Voltage dip< autoreclose time.
