Load profile record LoadProf

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 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.
