6.7 Measuring averaged values over an interval
Averaged values maximum
For each averaged value period calculated, the maximum value over the time interval is stored.
The maximum values can be reset to zero from the sentinel Energy display, the panel display
or the Hager Power setup software.
The exhaustive list of current and power demand values calculated according to the 3-pole or
4-pole version and the visualisation interface, is given in the table below:
The type of integration interval and the duration of the interval T are configurable on the
sentinel Energy display, the panel display and the Hager Power setup software.
N.B.
The Qtot Dmd, Stot Dmd, Max Q1 Dmd, Max Q2 Dmd, Max Q3 Dmd, Max Qtot Dmd and Max
Stot Dmd values depend on the arithmetic or vector summation convention for reactive and
apparent power (see §6.13 – Setting the reactive and apparent power calculation convention).
