Setting the protection function
To set the protection schemes, scheme switches and protection elements, do the following.
Protection elements are the measuring elements and timers.
Note:
Depending on the selected protection scheme and scheme switch setting, some of the scheme
switches and protection elements are not used and so need not be set. The protection function
setting menu of the GRZ100 does not display unnecessary setting items. Therefore, start by
setting the protection scheme, then set the scheme switch, then the protection elements.
As a result of the above, note that some of the setting items described below may not appear in
the actual setting.
•
Press 2 (= Trip) on the "Protection" screen to display the "Trip" screen.
