The results of all thresholds are processed using user-definable Boolean equations
and can be used to trigger the recording of fault, traveling waves, and disturbance
data.
The thresholds can be associated with power, voltage and current circuits, digital
channels or DC channels, as follows:
Voltage and Current: upper and lower limits, and rate of change:
o
ABC
- RMS value;
o
N
- neutral RMS value;
o
ABC1
- RMS value of fundamental component;
o
N1
- RMS value of neutral fundamental component;
o
𝐹
- frequency;
o
𝑆
+
- positive sequence;
o
S
−
- negative sequence;
o
𝑈
- imbalance;
o
THD
- total harmonic distortion.
o
VOSC
- voltage oscillation;
o
FRQOSC
- frequency oscillation (measured from voltage);
Power: upper and lower limits, and rate of change:
o
S
- combined apparent power;
o
S
1
- fundamental apparent power;
o
P
1
- fundamental active power;
o
Q
1
- fundamental reactive power.
Power: upper limits:
o
S𝑂𝑆𝐶
- power swing.
DC Transducers: upper and lower limits;
Digital channels: "L" to "H" transition, "H" to "L" transition, "H" and "L" level.;
Following parameters can be set for every defined threshold:
Parameters set for every defined threshold
Hysteresis
0 … 100 %
0.1 %
Hold time
0 … 0.5 s
0.01 s
To add new thresholds, select the A
DD NEW THRESHOLDS
section and choose the type of
threshold (voltage, current, power, digital, or DC). Each threshold is related to a circuit
or channel previously created.
