8.1 Adding New Voltage Thresholds
To add a voltage threshold fill in the following:
The S
OURCE
scroll box allows user to define a code of a voltage circuit used. No editing
allowed;
The Q
UANTITY
scroll box allows user to select the associated magnitude to be
monitored. For voltage circuits:

ABC
and
N
- magnitude or effective value;

ABC and N1 - phasors;

𝑆
+
- positive sequence;

𝑆
−
- negative sequence;

VIMB
- imbalance;

VFRQ - frequency;

VTHD - total harmonic distortion;

VOSC - voltage oscillation;

FRQOSC - frequency oscillation;

dABC and dN: - magnitude or effective value variation;

dABC1 and dN1 - phasor variation;

𝑑𝑆
+
- positive sequence variation;

𝑑𝑆
−
- negative sequence variation;

dVIMB - unbalance variation;

dVFRQ - frequency variation;

dVTHD - THD variation.
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 milliseconds, where the
threshold needs to be exceeded to be considered valid;
The H
YSTERESIS
text field allows user to enter a percentage of the V
ALUE
, the quantity
monitored needs to exceed that percentage in order to end the event and to reset
the threshold detector.
Once the threshold is created, it appears in the configuration interface menu. When
selecting the threshold, a screen shows the characteristics of the threshold selected,
as shown in Figure 27. It is possible to edit the value, hold time, and hysteresis.
