2.23 Average Values, Minimum and Maximum Values
Average, minimum and maximum values, minimum and maximum values of average
values, long-term average values, are calculated by the 7UT613/63x and can be read
out with the time reference (date and time of the last update).
The defined values of the average values and minimum and maximum values are to
be defined and up to 20 calculation units can be created with the help of DIGSI under
menu item „Extended Measuring Values 1-20“ in menu „Functional Scope“.
The parameter „Input Variable“ determines the measured value for which the calcula-
tion unit calculates the average values and the minimum/maximum values.
The following can be selected: phase currents of the measuring locations and sides,
voltages, power values, residual currents, frequency and differential protection values.
Selection of the input value varies depending on the protection device 7UT613/63x
and the settings of the configuration parameters.
With the parameter „Scope of the Extended Measured Values“, it can be determined
whether calculation units are to calculate average values, minimum and maximum
values or minimum and maximum values of long-term average values, or a combina-
tion thereof.
The calculated average values and minimum/maximum values appear in the device
menu „Measured Values“ in the menus „MV Measured Values“, „Average, Min/Max“
and „MV, Min/Max“ and in DIGSI in the menus „Minimum and Maximum Values“, „Av-
erage Values“ and „Minimum and Maximum Values of the Average Values“ under
menu „Min/Max and Average Values“ in menu „Measured Values“.
The results of the calculation unit can be reset via the set message/binary input
message in parameter „Resetting of the ext. Measured Values“ or via DIGSI, or the
integrated control panel.
