Multiple Setting Groups

Multiple Setting Groups
SEL-400 series relays have six independent setting groups. Each setting group
has complete relay settings and protection SEL
OGIC settings. The active setting
group can be:
➤ Shown or selected with the SEL ASCII serial port GROUP
command—see GROUP on page 14.31.
➤ Shown or selected from the front-panel LCD with the MAIN menu
Set/Show menu item and the Active Group submenu item as
described in Figure 4.31 on page 4.28.
➤ Selected with SELOGIC control equation settings SS1 through SS6.
Settings SS1 through SS6 have priority over all other selection
methods. Use remote bits in these equations to select setting groups
with Fast Operate commands as described in SEL Fast Meter, Fast
Operate, Fast SER Messages, and Fast Message Data Access on
page 15.28.
➤ Shown with DNP3 Objects 20 and 22 and selected with Objects 40
and 41.
Setting Groups: Application Ideas
Setting groups can be used for such applications as:
➤ Environmental conditions such as winter storms, periods of high
summer heat, etc.
➤ Hot-line tag that disables closing and sensitizes protection
➤ Commissioning and operation
