2.9.- Quality service
2.9.1.- Voltage out of limits
To calculate the variable when the voltage is out of limits, 5 variables must be programmed on
the meter: Nominal voltage, Threshold separation, Higher voltage set point, Lower voltage set
point, Minimum duration out-voltage.
The following information will be saved for each event: kind of event (Exceed voltage or faulty
voltage), start date and hour, end date and hour, with a resolution of a second.
A) Nominal voltage
This is the nominal voltage value of the supply (phase-phase voltage). This value will be
the one to take to consider is there is an event on the line: if the voltage is out of limit in the
upper lever or in the lower level. For CT meters this voltage will be the primary voltage.
B) Threshold separation
Is the limit value in % of the nominal voltage where all the values under this limit will be
considered as an interruption. If the value is below the limit, the data will treat as supply
interruption (see point 2.9.2).
C) Higher voltage set point
Is the limit value in % of the nominal voltage which is summed to the nominal voltage
where all the values above this limit are considered overvoltages. If this value is set to zero,
the meter will not register this kind of event.
D) Lower voltage set point
Is the limit value in % of the nominal voltage which is rested to the nominal voltage where
all the values below this limit are considered interruptions. If this value is set to zero, the
meter will not register this kind of event.
