- Voltage memory (current)
103 % of the pick-up voltage setting
97 % of the pick-up current setting
Reset time

Note!
• Voltage memory is activated only when all line voltages fall below set pick-up value.
• Voltage memory activation captures healthy situation voltage angles, one cycle before actual
activation (50Hz/20ms before “bolted” fault)
