4.4 Setting Event Detection [REC&EVENT]

4

A voltage swell, voltage dip or interruption of the nominal voltage is recorded
as an event.

See:

"Voltage Swell" (p. 110), "Voltage Dip" (p. 111), "Interruption" (p. 111)

Setting Voltage Swell, Dip and Interruption Events

Move to the setting item.

Select the screen.

Voltage Swell

Set a percentage larger than the nominal line voltage (default 110%).

Voltage Dip

Set a percentage smaller than the nominal line voltage (default 90%).

Interruption

Set a percentage smaller than the nominal line voltage (default 10%).

In all cases, an event is recorded when the threshold is breached in either direction (once
upon onset, and once again upon recovery).
Upon event recovery ("event out "), the continuous period and worst-case voltage swell val-
ues are displayed.
Upon event onset ("event in "), an event voltage fluctuation graph is recorded.

What is Voltage Swell?

Voltage swell is a rise of rms voltage, where a threshold is set above the nominal voltage.
When the rms voltage rises above the threshold, it is detected as an "event in (onset)" voltage swell
event. Subsequently, when the voltage falls back below the threshold (minus appropriate hystere-
sis), it is detected as an "event out (recovery)" voltage swell event.

What is Voltage Dip?

Voltage dip is the opposite of voltage swell, that is a fall of rms voltage where a threshold is set
below the nominal voltage.
When the rms voltage falls below the threshold, it is detected as an "event in (onset)" voltage dip
event. Subsequently, when the voltage rises back above the threshold (plus appropriate hystere-
sis), it is detected as an "event out (recovery)" voltage dip event.

What is Interruption?

This is the power suspension state when voltage drops to a threshold below the nominal voltage
and further below the voltage dip threshold.
When the rms voltage falls below the threshold, it is detected as an "event in (onset)" voltage in-
terruption event. Subsequently, when the voltage rises back above the threshold (plus appropriate
hysteresis), it is detected as an "event out (recovery)" voltage interruption event.
