Siemens SIPROTEC 5 User Manual

With the Phase-selective parameter, you define whether you want to set the threshold values of the level
triggers and of the gradient trigger phase-selectively or not.
Parameter Value Description
no
You do not adjust the threshold values of the level triggers and of the
gradient trigger phase-selectively.
The following threshold values apply to all 3 phases:
•
Max. (Non-phs sel.)
•
Min. (Non-phs sel.)
•
+dM/dt (Non-phs sel.)
•
-dM/dt (Non-phs sel.)
The phase-selective parameters can be set for each trigger, but are not
effective
yes
You adjust the threshold values of the level triggers and of the gradient
trigger phase-selectively.
The phase-selective parameters are then effective for the following triggers
•
Max. trigger
•
Min. trigger
•
dM/dt rise (/Filter time)
•
dM/dt drop (/Filter time)
Parameter: Max. active/Max. Trigger/Max. hysteresis
•
Default setting (_:9781:101) Max. active = yes
•
Default setting (_:9781:105) Max. (Non-phs sel.) = 1.200 A
•
Default setting (_:9781:118) Max. phs A = 1.200 A
•
Default setting (_:9781:119) Max. phs B = 1.200 A
•
Default setting (_:9781:120) Max. phs C = 1.200 A
•
Default setting (_:9781:113) Max. hysteresis = 0.980 p.u.
With the Max. active parameter, you activate the level trigger in order to monitor the RMS value of the
current and to prevent exceeding the set values.
Parameter Value
Description
yes
The RMS value of the current is monitored for overcurrent.
no
The RMS value of the current is not monitored for overcurrent.
If the Max. trigger does not operate phase-selectively, the set threshold value of the parameter Max.
(Non-phs sel.) applies to all phases.
If the Max. trigger operates phase-selectively, set the threshold values for the Max. trigger separately
for each phase. Then, the parameters Max. phs A, Max. phs B, and Max. phs C are effective.
The hysteresis is preset the factory to 0.980 p.u. of the parameter Max. (Non-phs sel.) and can be
adjusted.
Parameter: Min. active/Min. Trigger/Min. hysteresis
•
Default setting (_:9781:102) Min. active = yes
•
Default setting (_:9781:106) Min. (Non-phs sel.) = 0.800 A
•
Default setting (_:9781:121) Min. phs A = 0.800 A
•
Default setting (_:9781:122) Min. phs B = 0.800 A
•
Default setting (_:9781:123) Min. phs C = 0.800 A
•
Default setting (_:9781:114) Min. hysteresis = 1.020 p.u.
