3 - Histograms Page
Description
The Histogram page:
• This is the default initial page (accessed upon powering).
• It shows the histograms of the voltage and current measurements, acquired in real time by the trip unit.
Components of the page
The page appears as follow:

Figure 8
The following table provides a description of the various areas of the page:
Pos. Description
A
Y-axis of the histogram, with the measurements expressed as percentage of the nominal
values set.
B
Bars that represent the measurements of phase-to-phase voltages U12 U23 U31, and of the
phase currents L1 L2 L3 and of the neutral Ne:
• In blue: no alarm.
• In yellow: voltage or current in prealarm, compared with the thresholds set (see the
chapter "9 - Touch protections" from page 61, and the chapter "10 - Measuring Pro
protections" from page 75).
• In red: voltage or current in alarm, compared with the thresholds set (see the chapter
"9 - Touch protections" from page 61, and the chapter "10 - Measuring Pro protections"
from page 75).
C
X-axis of the histogram.
NOTE:
• The voltage histograms are shown with the Ekip Measuring accessory module.
• The Ne current histogram is shown with circuit-breaker configured with neutral.
