It is possible to configure several stages for different tasks:
•
Reporting only (with or without fault record)
Use this stage to report 1 or 2 faulty C-elements. To do this, set the parameters Max. no. of def.
elem. phs A, Max. no. of def. elem. phs B , Max. no. of def. elem. phs C , or
Max. no. of def. elem. to a small value (1 or 2). The parameter Operate delay can be set to 0.
If you would like to prevent the operate (tripping) and fault logging (fault log and fault record), set the
parameter Operate & flt.rec. blocked to yes.
If you would like to prevent only the operate (tripping) and the fault logging must occur, remove this
stage from the interface Trip to the circuit breaker (see also 5.4.2 Structure of the Function Group Inter-
faces with Circuit-Breaker Function Group).
•
Indication with delayed operate
Use this stage to report in case of some faulty C-elements and to set a relatively long time delay of the
operate, for example, 2 hours. During this time, the fault of the C-elements can be clarified. If it is
possible to find a solution, the counter status can be reset manually. This way, the stage drops out. If a
solution cannot be found within 2 hours, the stage trips and disconnects the capacitor bank.
•
Immediate operate
The stage is used to initiate the operate immediately after a larger number of C-elements became faulty.
