Siemens SIPROTEC 5 User Manual

Parameter: Max. Trigger Active/Max. Trigger/Max. Trigger Hysteresis
•
Default setting (_:9571:101) Max. trigger active = yes
•
Default setting (_:9571:105) Max. trigger = 120.000 V
•
Default setting (_:9571:113) Max. trigger hysteresis = 0.980 p.u.
With the Max. trigger active parameter, you activate the level trigger in order to monitor the voltage of
the fundamental component and prevent it from exceeding the set values.
Parameter Value Description
yes
The voltage of the fundamental component is monitored for overvoltage.
no
The voltage of the fundamental component is not monitored for over-
voltage.
The hysteresis is preset at the factory to 0.980 p.u. (equal to 2 %) of the parameter Max. trigger and can
be adjusted.
Parameter: Min. Trigger Active/Min. Trigger/Min. Trigger Hysteresis
•
Default setting (_:9571:102) Min. trigger active = yes
•
Default setting (_:9571:106) Min. trigger = 80.000 V
•
Default setting (_:9571:114) Min. trigger hysteresis = 1.020 p.u.
With the Min. trigger active parameter, you activate the level trigger in order to monitor the voltage of
the fundamental component for dropping below the set values.
Parameter Value
Description
yes
The voltage of the fundamental component is monitored for undervoltage.
no
The voltage of the fundamental component is not monitored for under-
voltage.
The hysteresis is preset at the factory to 1.020 p.u. (equal to 2 %) of the parameter Min. trigger and can
be adjusted.
Parameter: dM/dt Rise Active - dM/dt Rise (/Filter Time) - dM/dt Rise Hysteresis - Filter Time
•
Default setting (_:9571:103) dM/dt rise active = no
•
Default setting (_:9571:107) dM/dt rise (/Filter time) = 20.000 V
•
Default setting (_:9571:115) dM/dt rise hysteresis = 0.980 p.u.
•
Default setting (_:9571:112) Filter time = 2 periods
With the dM/dt rise active parameter, you activate the gradient trigger in order to monitor the positive
gradients of the voltage of the fundamental component using the set filtering time (input in periods).
Parameter Value
Description
yes
The positive gradient of the voltage of the fundamental component is moni-
tored.
no
The positive gradient of the voltage of the fundamental component is not
monitored.
The hysteresis is preset at the factory to 0.980 p.u. (equal to 2 %) of the parameter dM/dt rise (/Filter
time) and can be adjusted.
Parameter: dM/dt Drop Active - dM/dt Drop (/Filter Time) - dM/dt Drop Hysteresis - Filter Time
•
Default setting (_:9571:104) dM/dt drop active = no
•
Default setting (_:9571:108) dM/dt drop (/Filter time) = 20.000 V
