Description
The maximum power and mean and are the recordings of the measurements of total maximum
and average active power made by the release, and that can be displayed by selecting P Max
and P 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.
NOTE: with external communication, recordings of total, maximum and average
reactive and apparent power measurements are also available.
Correlated information
Every measurement is correlated by the following information:
• The time interval since the previous measurement.
• The value in kW.
• The date and time (referring to the internal clock).
• Graphical representation in the form of a histogram on a time axis.
NOTE:
• If current and voltage are lower than the minimum measurable values, the power
measurement indicates "..." instead of the value in kW.
• The graphical representation is in relation to 1 Pn, with maximum value of 1.25 Pn.
• Pn is calculated as the product of In and primary Vn
• If the value is negative, the corresponding bar is represented with different color to
those with positive value.
• When the parameter Measurement interval is modified , the release performs a
recording immediately.
