Description
The maximum and minimum Voltages are recordings of the measurements maximum and
minimum phase-to-phase voltages made by the release, and that can be displayed by selecting
U Max and U Min in the menu History - Measurements.
The interval between one measurement and the other can be set through the parameter
Measurement interval, available in the menu History.
The recordings can be reset through the command Reset measurements, available in the
menu History - Measurements.
Correlated information
Every measurement is correlated by the following information:
• The time interval since the previous measurement.
• The phase-to-phase voltage to which it refers, and value in Volt.
• The date and time (of the internal clock).
• Graphical representation in the form of a histogram on a time axis.
NOTE:
• If the value is less than 5 V, "..." is shown instead of the Volt values.
• The graphical representation is in relation to 1 Vn, with maximum value of 1.25 Vn.
• When the parameter Measurement interval is modified , the release performs a
recording immediately.
