Minimum/Maximum Values
Function Description of Minimum/Maximum Values
Minimum and maximum values can be formed based on different measured or calculated measurands:
•
Operational measured values
•
Symmetrical components
•
Selected values
You can set which measurand will be used. The measurands for the minimum/maximum formation are loaded
from DIGSI.
Calculation and resetting of the minimum and maximum values are controlled through settings. The settings
describe the following points:
•
Memories of the minimum/maximum values are reset to 0 cyclically or not at all.
(Setting Min/Max cyclic reset )
•
Point in time when the memories of the minimum/maximum values are reset to 0.
(Setting Min/Max reset each and setting Min/Max reset minute )
•
Point in time at which the cyclical reset procedure of the minimum/maximum values begins (after the
parameterization)
(Setting Min/Max days until start )
The following figure shows the effect of the settings.
