2.5.2. LOAD PROFILE
The smART P500 relay is able to store, at the end of each period of time set by the
user, the average value of any group of its Actual Values, and also the accumulated
value registered for any parameter from the group Miscellaneous Accumulators in that
period (acting as a pulse recorder).
This information is stored in the internal memory of the protection under the name Load
Profile. Using the information stored in these profiles it is possible to make studies of the
load profile, stability, energy savings, etc.
Up to 25 user selectable parameters can be pre-programmed within the group of
instantaneous parameters and accumulators.
2.5.2.1. PARAMETERS
2.5.2.1.1. INSTATANEOUS VALUES
This group includes the 45 parameters shown in Table 2-32. Their values are
updated every second.
