3.4.5 Transient Mode
The Transient mode
is used to record voltage or current transients.
Select
to configure the Transient mode
3.4.5.1 Voltage Thresholds
Press
to configure the voltage thresholds
For
Number of cycles before trigger event
, choose the number of cycles
between 1 and 4 that will occur before the transient recording is triggered
For
Threshold set-up
, define the relationship between the thresholds and
voltage inputs. You can enter thresholds from 0 V to 9999 kV
If
4V
is selected, every voltage input has the same threshold, so there is
only one threshold to configure
If
3V+VN
is selected, every voltage input has the same threshold, but the
neutral has a different threshold. There are two thresholds to configure
If
V1+V2+V3+VN
is selected, every voltage input and the neutral have
different thresholds, so there are four thresholds to configure
3.4.5.2 Current Thresholds
Select
to configure the current thresholds
For
Number of cycles before trigger event
, choose the number of cycles
between 1 and 4 that will occur before the transient recording is triggered
For
Threshold set-up
, define the relationship between the thresholds and
current inputs. You can enter thresholds from 0 mA to 9999 kA
If
4A
is selected, every current input has the same threshold, so there is
only one threshold to configure.
If
3A+AN
is selected, every current input has the same threshold, but the
neutral has a different threshold. There are two thresholds to configure.
If
A1+A2+A3+AN
is selected, every voltage input and the neutral have
different thresholds, so there are four thresholds to configure.
3.4.5.3 Shock Wave Thresholds
Select
to configure the voltage thresholds of shock waves with respect
to earth
For
Threshold set-up
, define the relationship between the thresholds and
voltage inputs. You can enter thresholds from 0 V to 2000 MV
