3.24.3 Functionality
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 higher 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.
