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

Correlated information
Al measurements are correlated with 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 referred to 1 In, with a maximum value of 1.25 In
•
When the parameter “Monitor time” is modified, the trip unit performs an immediate recording.
Peak factor
Path
Main page - Menus - Measurements
Description
The selection of
Peak factor
in the menu
Measurements
allows you to display real time measurements 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.
