4.11 Setting Groups
ASIPROTEC
®
4 device has up to four setting groups A through D. The setting options
for each group are the same; however, the applied settings can be, and are typically
intended to be, different in each group. The active setting group can easily be changed
while the device is in-service. A major advantage of multiple setting groups is the ca-
pability of optimizing the protection and control for the existing configuration of the net-
work being protected. In other words, the protection and control can be changed as
the network changes.
The setting groups are saved in the device. The setting groups can be changed during
operation using DIGSI
®
4, from the operator control panel on the device, by triggering
binary inputs, or via the system interface.

Note:
Settings that are common to all protective functions, of one setting group are available
in Power System Data 2.
