Voltage dip
Signal
Meaning
Voltage dip (digital)
Active, if the half period RMS value of at least one
phase is lower than the limit.
Voltage dip Start
Current time
– start_time, in seconds, while the
event is running.
Voltage dip Duration
Previous duration of events, in seconds, while the
event is running.
Voltage dip Min
Minimum half period RMS value, in V, while the
event is running.
The limit is increased by the hysteresis, if the event is active.
The limit is calculated as percentage value of the rated voltage or as percentage value
of the floating reference value.
Note: this value is calculated for each phase separately.
Voltage swell
Signal
Meaning
Voltage swell (digital)
Active, if the half period RMS value of at least one
phase is higher than the limit.
Voltage swell Start
Current time
– start_time, in seconds, while the
event is running.
Voltage swell Duration
Previous duration of events, in seconds, while the
event is running.
Voltage swell Max
Maximum half period RMS value, in V, while the
event is running.
The limit is reduced by the hysteresis, if the event is active.
The limit is calculated as percentage value of the rated voltage or as percentage value
of the floating reference value.
Note: this value is calculated for each phase separately.
Voltage drop
Signal
Meaning
Voltage drop (digital)
Active, if the half period RMS value of all phases
of a supply voltage grid is lower than the limit.
Voltage drop Start
Current time
– start_time, in seconds, while the
event is running.
Voltage drop Duration
Previous duration of events, in seconds, while the
event is running.
Voltage drop Min
Minimum half period RMS value, in V, while the
event is running.
The limit is increased by the hysteresis, if the event is active.
The limit is calculated as percentage value of the rated voltage.
