Application and Setting Notes
Interface to Circuit-Breaker Function Group
The Capacitor bank protection function group is linked to one Circuit-breaker function group. This Circuit-
breaker function group is assigned to the circuit breaker of the capacitor bank.
Protected Object/Equipment Data (FB General)
The following application and setting notes apply for the general data. The data are configured in the function
block General of the Capacitor bank function group and apply for all functions in the function group.
Parameter:
Capacitor reference curr.
•
Default setting
(_:14641:101) Capacitor reference curr. = 1000 A
With the
Capacitor reference curr.
parameter, you set the reference current for the capacitor bank to
be protected. This
Capacitor reference curr.
specified here is the reference value for the percentage-
measured values and setting values made in percentages.
Depending on the user philosophy, the reference value could be the capacitor-bank rated current, which
includes harmonics, or the capacitor-bank fundamental current.
Parameter:
Capacitor reference volt.
•
Default setting
(_:14641:102) Capacitor reference volt. = 400.00 kV
With the parameter
Capacitor reference volt.
, you set the reference voltage of the capacitor bank to
be protected. This
Capacitor reference volt.
specified here is the reference value for the percentage-
measured values and setting values made in percentages.
