Current Triggering
Your PQube triggers events on the Phase Current channels, the Neutral Current channel, and the
Earth Current channel. There are two ways to trigger a current event:
Overcurrent
You can set the overcurrent threshold by editing the tags called Level_Threshold_In_Amps and the
Level_Hysteresis_In_Amps in your Setup.ini file.
Your PQube will trigger if any RMS current exceeds the level threshold.
Inrush
Inrush triggers have thresholds for magnitude and time. You can set these values by locating the
tags called Inrush_Threshold_In_Amps and Inrush_Threshold_In_Cycles in your Setup.ini file. If
the current increases by the Inrush Threshold value or more, within the specified time period or
less, the PQube will trigger an inrush current event.
Trends and Statistics Recordings
Your PQube records minimum/ average/
maximum strip charts, cumulative probability
statistics, and load duration statistics. By
default, your PQube will record all of this
information over the course of each day, week,
and month.
Trends and statistics recordings give you
information about what happened on the
systems that your PQube is monitoring, even if
there weren’t any events.
These recordings include readings every
minute (for daily recordings) or every 5 minutes
(for weekly and monthly recordings). Your
PQube contains the average reading every one
or five minutes as well as the minimum and
maximum updated five times a second.
