•
Voltage swell hysteresis: A voltage swell hysteresis value can be defined at
a different value for the voltage swell event starting and finishing. Therefore, a
voltage swell event starts when the voltage swell threshold is exceeded and
ends when the voltage value is below the value defined by subtracting the
voltage swell hysteresis value from the voltage swell threshold.
•
% of voltage dip threshold: The detection of a voltage dip depends on the
value set for this point (% of the rated voltage). Every semi-cycle where the
RMS value is below the defined limit is said to be a voltage dip. A record will
be saved in the events file (EVQ) every time this limit is exceeded indicating
the minimum voltage value detected, the average voltage value and the
duration of the voltage dip event.
•
Voltage dip hysteresis: A voltage dip hysteresis value can be defined at a
different value for the voltage dip event starting and finishing. Therefore, a
voltage dip event starts when the voltage dip threshold is not reached and
ends when the voltage value is over the value defined by adding the voltage
dip hysteresis value to the voltage dip threshold.
•
% of interruption threshold: The detection of an interruption depends on the
value set for this point (% of the rated voltage). Every semi-cycle where the
RMS value is below the defined limit is said to be an interruption. A record will
be saved in the events file (EVQ) every time this limit value is exceeded
indicating the minimum voltage value detected, the average voltage value and
the duration of the interruption event.
•
Interruption hysteresis: An interruption hysteresis value can be defined at a
different value for the interruption event starting and finishing. Therefore, an
interruption event starts when the interruption threshold is not reached and
ends when the voltage value is over the value defined by adding the
interruption hysteresis value to the interruption threshold.
•
STD file recording period. Part of the memory allocated for this file,
expressed in days. This is a not modifiable value, it will depend on the
recording period and the memory allotted for other files.
•
Number of recordings in the EVE file. Part of the memory allocated for the
incidents file, expressed as the number of incidents.
•
Number of recordings in the EVQ file.
Part of the memory allocated for the
events file, expressed as the number of events.
•
H24 file size (in weeks): Indication of the H24 file size.
