Siemens SIPROTEC 5 User Manual

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: dM/dt Rise Active - dM/dt Rise (/Filter Time) - dM/dt Rise Hysteresis - Filter Time
•
Default setting (_:9691:103) dM/dt rise active = no
•
Default setting (_:9691:107) dM/dt rise (/Filter time) = 11.547 V
•
Default setting (_:9691:115) dM/dt rise hysteresis = 0.980 p.u.
•
Default setting (_:9691:112) 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 in the negative-sequence system using the set filtering time (input in periods).
Parameter Value Description
yes
The positive gradient of the voltage in the negative-sequence system is
monitored.
no
The positive gradient of the voltage in the negative-sequence system 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.
