5.5GROUPED ELEMENTS 5.5.1 OVERVIEW
Each protection element can be assigned up to six different sets of settings according to Setting Group designations 1 to 6.
The performance of these elements is defined by the active Setting Group at a given time. Multiple setting groups allow the
user to conveniently change protection settings for different operating situations (e.g. altered power system configuration,
season of the year). The active setting group can be preset or selected via the
SETTING GROUPS
menu (see the Control Ele-
ments section later in this chapter). See also the Introduction to Elements section at the beginning of this chapter.
