Siemens SIPROTEC 5 - Settings

•
Default setting (_:9571:116) dM/dt drop hysteresis = 0.980 p.u.
•
Default setting (_:9571:112) 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 voltage of the fundamental component using the set filtering time (input in periods).
Parameter Value Description
yes
The negative gradient of the voltage of the fundamental component is
monitored.
no
The negative 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 drop (/Filter
time) and can be adjusted.
