f<< Del
0,50 s
Rst f<
[100% f< / +0,2% f< / 47,5 Hz]
Thresholds for frequency measurement hysteresis.
Options:
100% f<:
the threshold is set to the underfrequency limit
+0,2% f<:
increase of the underfrequency limit by 0,2% of the limit value
47,5 Hz:
reset value set to 47,5 Hz
Default setting:
100% f<
Rst f>
[100% f> / -0,2% f> / 50,05 Hz]
Thresholds for frequency measurement hysteresis.
Options:
100% f>:
the threshold is set to the overfrequency limit
-0,2% f>:
decrease of the overfrequency limit by 0,2% of the limit value
50,05 Hz:
reset value set to 50,05 Hz
Default setting:
100% f>
f Trp BO
[Trp 1 / Trp 2 / Trp 1+2 / None]
Selection of trip binary output for frequency protections.
Default setting: None
LOM
Vs Lim
[°]
Threshold for activating the Vector shift protection.
Step:
1°
Range:
1 -
50°
0° = OFF
the Vector shift protection is disabled
Default setting
: 10°
ROCOF
[Hz/s]
Threshold for activating the Rate of change of frequency (ROCOF) protection.
Step:
0,01 Hz/s
Range:
0,00 - 10,0 Hz/s
0 = OFF, the ROCOF protection is disabled
Default setting: 0 Hz/s
ROCOF filt
[-]
Determinates number of periods considered for evaluating ROCOF protection. Higher number means
lower sensitivity and longer evaluation time. Lower number means increased sensitivity and shorter
evaluation time.
Step:
1
Range:
0 - 100
Default setting: 5
LOM Init Del
[s]
Delay for what the Loss of Mains (LOM, i.e. Vector shift and ROCOF) protection is disabled after
applying valid measured voltage (stepping into the operational area of voltage and frequency).
Step:
1 s
Range:
0 - 600 s
Default setting: 3 s
