Minimum/Maximum Values of Real-Time Measurements

Minimum and maximum measurements take into account the absolute value of real-time measurements. Therefore the following rule applies:

0<10<200<-400<600<-3800.

In this case:

NOTE: This rule does not apply for the power factor (PF) and for the fundamental power factor (cosϕ):

PFmax (or cosϕ max.) is obtained for the smallest positive value of PF (or cosϕ).
PFmin (or cosϕ min.) is obtained for the highest negative value of PF (or cosϕ).

The reset minimum/maximum command (command code = 46728) can reset the content of the minimum/maximum real-time measurement registers.

Registers 1300 to 1599 hold the minimum values of real-time metering parameters:

The register of the minimum value of a real-time metering parameter is equal to the register of the real-time metering parameter plus 300.

Examples
- Register 1300 holds the minimum value of the phase-to-phase voltage V12 (register 1000).
- Register 1316 holds the minimum value of the current on phase 1 (register 1016).
The order of the registers is the same as that of the real-time metering variables.
The scale factors of the minimum values are the same as those of the real-time metering parameters.
The minimum values of unbalance current and unbalance voltage are not available.
The minimum values of Imin (register 1026), Vmax (register 1145), and Vmin (register 1146) are not available.

Registers 1600 to 1899 hold the maximum values of real-time metering parameters:

The register of the maximum value of a real-time metering parameter is equal to the register of the real-time metering parameter plus 600.

Examples
- Register 1600 holds the maximum value of the phase-to-phase voltage V12 (register 1000).
- Register 1616 holds the maximum value of the current on phase 1 (register 1016).
The order of the registers is the same as that of the real-time metering variables.
The scale factors of the maximum values are the same as those of the real-time metering parameters.
The maximum values of Imin (register 1026), Vmax (register 1145), and Vmin (register 1146) are not available.
