Voltage gap
In time intervals
t1
and
t3
in
, two voltage gaps are illustrated. The duration of the event
matches the time the signal is below the set threshold value (
“6.2.2.- OVERVOLTAGES AND GAPS"
), in
this example it is 90% of the nominal voltage.
Voltage interruption
In the time interval
t2
in
, an outage or interruption event is shown. The duration of the event
matches the time the signal is below the set threshold value (
“6.2.3.- INTERRUPTION AND HYSTERESIS
), in this example it is 10% of the nominal voltage, plus the time it takes for the signal to in-
crease from the value, including a 2% hysteresis.
