Min/Max Measurement Setup
Minimum and maximum values are calculated by the 7SD80. Time and date of the last update of the values
can also be read out.
Functional Description
Minimum and Maximum Values
The minimum and maximum values for the three phase currents
Ι
x
, the three phase voltages V
x-N
, the phaseto-
phase voltages V
xy
, the positive sequence component
Ι
1
and V
1
, the active power P, reactive power Q, and
apparent power S, the frequency, and the power factor cos φ a formed as primary values including the date
and time they were last updated.
The minimum and maximum values of the long-term mean values listed in the next section are also calcu-
lated.
The minimum and maximum values can be reset at any time via binary inputs or by using the integrated
control panel or the DIGSI software. Additionally, the reset can be carried out cyclically, starting at a preset
point of time.
Setting Notes
Minimum and Maximum Values
The minimum and maximum values can be reset automatically at a programmable point in time. This feature
can be activated by setting address 2811
MinMax cycRESET
to
YES
.
At address 2812
MiMa RESET TIME
you can define the point of time when resetting takes place (minute of
the day).
Address 2813
MiMa RESETCYCLE
allows you to define the resetting cycle (in days).
At address 2814
MinMaxRES.START
you can define when the cyclic process of forming the minimum and
maximum values begins (in days, counted from the time of parameterization).
