The is the length of time of the disturbance. If the disturbance is either a sag or a
DURATION
swell the duration will be recorded in cycles with a maximum possible value of 1 minute
(3600 cycles at 60Hz).
The represents the average level in volts for the disturbance.
VOLTAGE LEVEL
The voltage disturbance recorder is independent from the event recorder. The alarm
events will record normally as per the conditions set within the
settings menu, regardless whether the voltage disturbance recorder is enabled or of
the sag/swell level.
If an undervoltage/overvoltage alarm occurs, it is immediately recorded as an event (if
enabled). On the other hand, the voltage disturbance is recorded, if enabled, once the
voltage level returns to nominal and the condition is complete. As a result, the time
recorded in the event recorder is the start time of the alarm condition, while the time
recorded in the disturbance recorder is the end time of the condition.
