NOTE:
for the details on the pages, see the chapter Menu pages and menus, and
the paragraph Measurement history, beginning from page 65.
Description
The maximum and minimum currents are the recordings of the measurements of the maximum
and minimum phase currents performed by the release, and that can be displayed by selecting
I Max
and
I Min
in the menu
History - Measurements
.
The interval between one measurement and the other can be set through the parameter
Measurement interval

Correlated information
Every measurement is correlated by the following information:
• The time interval since the previous measurement.
• The phase to which it refers, and value in Amperes.
• The date and time (referring to the internal clock).
• Graphical representation in the form of a histogram on a time axis.
NOTE:
•
If the value is less than 0.03 In, “…” is shown instead of the value in Amperes.
•
The graphical representation is in reference to 1 In, with a maximum value of 1.25
In
•
When the parameter “Measurement interval” is modified, the release performs a
recording immediately.
Peak Factor
Path
Main page - Menus - Measurements
Description
The selection of
Peak factor
in the menu
Measurements
allows you to display the
measurements in real time of the peak factors of the phase currents.
The measurements are expressed as a ratio between the peak values and RMS values, for
each individual phase.
