
dABC1 and dN1 - phasor variation;

+
���� - positive sequence variation;

−
���� - negative sequence variation;

dIIMB

dITHD - 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 quantity in %, whose the value needs
YSTERESIS
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 appears in the configuration interface menu. When
selecting the threshold, a screen shows the characteristics of the threshold selected,
as shown in the figure below. It is possible to edit the value, hold time, and hysteresis.
