the setting values of their parameters are continuously optimized according to the
conditions in the power system.
Operational departments can plan for different operating conditions in the primary power
system equipment. The protection engineer can prepare the necessary optimized and pre-
tested settings in advance for different protection functions. different groups of setting
parameters are available in the IED. Any of them can be activated through the different
programmable binary inputs by means of external or internal control signals.
The four different groups of setting parameters are available in the IED. Any of them can
be activated through different inputs by means of external programmable binary or
internal control signals.

Setting guidelines
The setting
ActiveSetGrp
, is used to select which parameter group to be active. The active
group can also be selected with configured input to the function block ACTVGRP.
The parameter
MaxNoSetGrp
defines the maximum number of setting groups in use to
switch between. Only the selected number of setting groups will be available in the
Parameter Setting tool (PST) for activation with the ACTVGRP function block.

Application
The protection and control IEDs may have a complex configuration with many included
functions. To make the testing procedure easier, the IEDs include the feature that allows
individual blocking of all functions except the function(s) the shall be tested.
This means that it is possible to see when a function is activated or trips. It also enables the
user to follow the operation of several related functions to check correct functionality and
to check parts of the configuration, and so on.
