Siemens SIPROTEC 5 User Manual

With the Min. trigger active parameter, you activate the level trigger in order to monitor the power
frequency and prevent it from dropping below the set value.
Parameter Value Description
yes
The power frequency is monitored for dropping below the set value.
no
The power frequency is not monitored for dropping below the set value.
The hysteresis is preset at the factory to 1.002 p.u. (equal to 0.2 %) 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 (_:9721:105) dM/dt rise active = no
•
Default setting (_:9721:106) dM/dt rise (/Filter time) = 0.100 Hz
•
Default setting (_:9721:115) dM/dt rise hysteresis = 0.998 p.u.
•
Default setting (_:9721:112) 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 sum apparent power using the set filtering time (input in periods).
Parameter Value Description
yes
The positive gradient of the power frequency is monitored.
no
The positive gradient of the power frequency is not monitored.
The hysteresis is preset at the factory to 0.998 p.u. (equal to 0.2 %) 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 (_:9721:107) dM/dt drop active = no
•
Default setting (_:9721:108) dM/dt drop (/Filter time) = 0.100 Hz
•
Default setting (_:9721:116) dM/dt drop hysteresis = 0.998 p.u.
•
Default setting (_:9721:112) 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 power frequency using the set filtering time (input in periods).
Parameter Value
Description
yes
The negative gradient of the power frequency is monitored.
no
The negative gradient of the power frequency is not monitored.
The hysteresis is preset at the factory to 0.998 p.u. (equal to 0.2 %) of the parameter dM/dt drop (/
Filter time) and can be adjusted.
