If
4VE
is selected, every voltage input has the same threshold, so there is
only one threshold to configure.
If
3VE+VNE
is selected, every voltage input has the same threshold. The
neutral has a different threshold, so there are two thresholds to configure.
If
V1E+V2E+V3E+VNE
is selected, every voltage input and the neutral have
different thresholds, so there are four thresholds to configure.
3.4.5.4 Rapid Capture Configuration
Press
to rapidly configure a transient capture
For
Duration
, enter the length of the capture between 1 min and 99 d
For
Max count
, enter the maximum number of transients in the capture
between 1 and 1000
For
Name
, enter the capture’s name (up to 8 characters long) using capital
letters (A-Z), numbers (0-9), and symbols (&, _, and -)
3.4.6 Inrush Current Mode
The Inrush Current mode
is used to capture inrush currents.
Select
to configure the inrush current
mode
For
Triggering filter
, determine whether the inrush current threshold will
apply to all 3 current inputs (3A) or only one of them (A1, A2, or A3)
Enter a current threshold between 0 mA to 9999 kA for the selected
current inputs. The threshold detects the appearance of an additional
current by accounting for the current present
For
Hysteresis
, choose from 0 % to 100 % for the capture’s hysteresis
The first threshold triggers the capture, and the hysteresis stops it.
For more information about the hysteresis, refer to § 20.5. Setting the
hysteresis to 100 % is equivalent to not having a stop threshold.
Press
to configure an inrush current capture
For
Duration
, enter the length of the capture between 1 min and 99 d
For
Max count
, you cannot modify this field. It is grayed-out because the
number of captures is always 1
For
Name
, enter the capture’s name (up to 8 characters long). The name
can include capital letters (A-Z), numbers (0-9), and symbols (&, _, and -)
