Resetting/Setting the Counters
You can reset or set the counters of group 1 and group 2 via:
•
On-site operation panel directly on the device
•
Online DIGSI connection to the device
•
Binary input
>Reset all counters
(only reset of all counters)
•
Communication connection with the control center
You can directly set or reset the counters via IEC 61850 by setting the counter values to the desired value. If
you want to reset the counters via DNP3, IEC 60870-5-103, Modbus, or IEC 60870-5-104, an additional config-
uration with CFC is necessary. For more information, refer to chapter 7.4.3.2 Application and Setting Notes.

You can find the value of the parameter Rated primary current of the preceding table in the chapter
6.1.8 Settings according to the specified parameter MP selection.

. The normalization is carried out no matter if the parameter Normalization
with Ic is set to yes or no. I
comp.,vect.
keeps its value unchanged until the next compensation occurs.

Definition of the Group and Fault Location with the Capacitor in H Connection
If the capacitor is designed in an H connection, the following definition is assumed:
