Figure 7-19
Definition for the Fault-Location Information
The black dot indicates the orientation of the current transformer. For the connection of the current trans-
former shown in the previous figure, the following definition applies:
•
Group 1: C1 and C4
•
Group 2: C2 and C3
In order to determine the fault location (group 1 or 2) correctly, use the parameter Capacitor element
type (in FB General of the Capacitor bank function group) to tell the device whether the elements of the
capacitor bank have internal fuses or not.
Non-Compensated Status
If no compensated values are available and the stage has been set to use such values, the stage will be
blocked. The readiness of the stage turns to
Warning . This condition will be reported on the function stage
(indication Alg. not compensated ).
