Settings - Siemens 7SJ82 Manual

Parameter: Trip interface contains
•
Default setting (_:13921:101) Trip interface contains = operate (grid)
The stage provides 2 operate signals, the
You use the Trip interface contains parameter to define whether one or none of them will be
forwarded to the trip interface of the circuit-breaker interaction. The selected operate signal will trip the circuit
breaker that has been connected to the protection function group.
The setting depends on the specific application.
Parameter: Q sign
•
Default setting (_:13921:102) Q sign = not reversed
The default directions of the positive reactive-power flow Q and the forward direction of the short-circuit
protection are identical, in the direction of the main protected object (for example, a feeder). You use the Q
sign parameter to reverse the sign and therefore the direction of the reactive-power flow Q. This reversal
may be required for specific application, where the main protected object (for example, a line towards the
main power systems) is in different direction to the power-generation facility.

Description
The protected object is in the same direction as the power-gener-
ation facility.
The protected object is not in the same direction as the power-
generation facility.
