Adding New Voltage Thresholds

To add a voltage threshold fill in the following:
The S scroll box allows user to define a code of a voltage circuit used. No editing
OURCE
allowed;
The Q scroll box allows user to select the associated magnitude to be
UANTITY
monitored. For voltage circuits:

ABC and N

ABC and N1

+
��
- positive sequence;

−
�� - negative sequence;

VIMB
- imbalance;

VFRQ - frequency;

VTHD - total harmonic distortion;

VOSC
- voltage oscillation;

FRQOSC - frequency oscillation;

dABC and dN:

dABC1 and dN1 - phasor variation;

+
���� - positive sequence variation;

−
���� - negative sequence variation;

dVIMB - unbalance variation;

dVFRQ - frequency variation;

dVTHD - THD variation.
The O scroll box allows user to select greater than or less than for analog
PERATOR
magnitude;
The V text field allows user to enter the magnitude value associated with greater
ALUE
than or less than operator;
The H text field allows user to enter the time in milliseconds, where the
OLD TIME
threshold needs to be exceeded to be considered valid;
The H text field allows user to enter a percentage of the V
YSTERESIS
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.
