Siemens SIPROTEC 5 User Manual

With the Min. trigger active parameter, you activate the level trigger in order to monitor the RMS value
of the voltage and to prevent it from dropping below the set value.
Parameter Value Description
yes
The RMS value of the voltage is monitored for undervoltage.
no
The RMS value of the voltage is not monitored for undervoltage.
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 (_:9601:103) dM/dt rise active = no
•
Default setting (_:9601:107) dM/dt rise (/Filter time) = 20.000 V
•
Default setting (_:9601:115) dM/dt rise hysteresis = 0.980 p.u.
•
Default setting (_:9601:112) 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 RMS value of the voltage using the set filtering time (input in periods).
Parameter Value Description
yes
The positive gradient of the RMS value of the voltage is monitored.
no
The positive gradient of the RMS value of the voltage 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 (_:9601:104) dM/dt drop active = no
•
Default setting (_:9601:108) dM/dt drop (/Filter time) = 20.000 V
•
Default setting (_:9601:116) dM/dt drop hysteresis = 0.980 p.u.
•
Default setting (_:9601:112) Filter time = 2 periods
With the dM/dt drop active parameter, you activate the gradient trigger in order to monitor the negative
gradients of the RMS value of the voltage using the set filtering time (input in periods).
Parameter Value
Description
yes
The negative gradient of the RMS value of the voltage is monitored.
no
The negative gradient of the RMS value of the voltage is not monitored.
The hysteresis is preset at the factory to 0.980 p.u. (equal to 2 %) of the parameter dM/dt drop (/Filter
time) and can be adjusted.
Application and Setting Notes Trig V Fund (Fundamental Component)
Parameter: Mode
•
Default setting (_:9571:1) Mode = off
With the Mode parameter, you activate the trigger for normal operation (On) or the test mode (Test).
Parameter Value
Description
on
The function block Trig V Fund. is activated and the fundamental compo-
nent is monitored on the basis of the set trigger parameter.
off
The function block Trig V Fund. is deactivated.
test
The function block Trig V Fund. is activated for test purposes.
