Factory settings restoration

In case of configuration data loss or any other file system error that prevents the

protection relay from working properly, the whole file system can be restored to

the original factory state. All default settings and configuration files stored in the

factory are restored. For further information on restoring factory settings, see the

operation manual.

Figure 108: Function block

The protection relay is provided with a load profile recorder. The load profile feature

stores the historical load data captured at a periodical time interval (demand

interval). Up to 12 load quantities can be selected for recording and storing in a

nonvolatile memory. The value range for the recorded load quantities is about eight

times the nominal value, and values larger than that saturate. The recording time

depends on a settable demand interval parameter and the amount of quantities

selected. The record output is in the COMTRADE format.

Selectable quantities are product-dependent.
