5.5 GROUPED ELEMENTS

Each protection element can be assigned up to 8 different sets of settings according to SETTING GROUP designations 1
to 8. 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 con-
figuration, season of the year). The active setting group can be preset or selected via the SETTING GROUPS menu (see
the CONTROL ELEMENTS section). See also the INTRODUCTION TO ELEMENTS section at the front of this chapter.
