A The <A
PPLY ALL
> button allows user to apply the hold time or the hysteresis for all
thresholds.
B The <R
EMOVE
> button allows user to delete the threshold.
8.3 Adding New Power Thresholds
To add a power threshold, fill in the following:

The S
OURCE
scroll box allows user to define a code of a power circuit used. No
editing allowed.

The Q
UANTITY
scroll box allows user to select the associated magnitude to be
monitored. For power circuits:
 S - total apparent power;

S1 - apparent power;
 P1 - active power;

Q1 - reactive power;

dS - total apparent power variation;
 dS1 - apparent power variation;

dP1 - active power variation;

dQ1
- reactive power variation;

SOSC - power swing;

The O
PERATOR
scroll box allows user to select greater than or less than for analog
magnitude.

The V
ALUE
text field allows user to enter the magnitude value associated with
greater than or less than operator.

The H
OLD TIME
text field allows user to enter the time in seconds, where the
threshold needs to be exceeded to be considered valid. For the SOSC power
threshold, this field is called O
SCILLATION
T
IME
;

The H
YSTERESIS
text field allows user to enter a quantity in % , whose value needs
to be smaller in relation to the threshold to determine the end of the event and
to reset the threshold detector.
Once the threshold is created, it shows in configuration interface menu. When
selecting the threshold, a screen shows the characteristics of the threshold selected,
as shown in
Figure 29 . It is possible to edit the value, hold time, and hysteresis.
