Harmonics:
Harmonic distortion:
The
QNA-303
will calculate and record into memory
the value of the voltage average harmonic distortion detected in the
monitored power system.
Harmonic content:
The
QNA-303
will calculate and record into memory
the average value of the individual harmonic distortion rate of each voltage
harmonic in the monitored power system (up to the 25
th
harmonic)
6.2.2.- Events file (EVQ)
The analyzer also records an events file that contains information on
any incidence happening detected in the monitored power system. Following data is
saved about each event:
Event date:
Indication of the instant of the event occurrence. This value is
obtained with an accuracy of one semicycle.
Type of event:
Indication of the event type, that is, a voltage dip, a voltage
swell or an interruption. These events are defined in accordance to the
QNA-303
setup. (See Section
¡Error! No se encuentra el origen de la referencia.
). The type
of event also identifies the phase this event has happened over.
Duration of the event:
The number of the semicycles that the event has
lasted.
Average voltage of the event:
The voltage average value over the event
happening period.
Maximum/minimum voltage of the event:
In case of an interruption or
voltage dip event, the voltage minimum value obtained during the event happening
period. In case of a voltage swell even, the maximum values will be recorded.
Previous voltage to the event:
The voltage value before the event
occurrence is recorded.
