Siemens SIPROTEC 5 User Manual

Parameter Value Description
on
The function block I RMS Trig is activated and the RMS value of the current
is monitored according to the set trigger parameter.
off
The function block I RMS Trig is deactivated.
test
The function block I RMS Trig is activated for test purposes.
Parameter: Max. Trigger Active/Max. Trigger/Max. Trigger Hysteresis
•
Default setting (_:9781:101) Max. trigger active = yes
•
Default setting (_:9781:105) Max. trigger = 1.200 A
•
Default setting (_:9781:113) Max. trigger hysteresis = 0.980 p.u.
With the Max. trigger active parameter, you activate the level trigger in order to monitor the RMS value
of the current and to prevent exceeding the set values..
Parameter Value Description
yes
The RMS value of the current is monitored for overcurrent.
no
The RMS value of the current is not monitored for overcurrent.
The hysteresis is preset the factory to 0.980 p.u. of the parameterMax. trigger and can be adjusted.
Parameter: Min. Trigger Active/Min. Trigger/Min. Trigger Hysteresis
•
Default setting (_:9781:102) Min. trigger active = yes
•
Default setting (_:9781:106) Min. trigger = 0.800 A
•
Default setting (_:9781:114) Min. trigger hysteresis = 1.020 p.u.
With the Min. trigger active parameter, you activate the level trigger in order to monitor the RMS value
of the current and to prevent it from dropping below the set values.
Parameter Value
Description
yes
The RMS value of the current is monitored for undercurrent.
no
The RMS value of the current is not monitored for undercurrent.
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 (_:9781:103) dM/dt rise active = no
•
Default setting (_:9781:107) dM/dt rise (/Filter time) = 0.300 A
•
Default setting (_:9781:115) dM/dt rise hysteresis = 0.980 p.u.
•
Default setting (_:9781:112) 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 current, using the set filtering time (input in periods).
Parameter Value
Description
yes
The positive gradient of the RMS value of the current is monitored.
no
The positive gradient of the RMS value of the current 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.
