Transients - AEMC PowerPad III 8336 User Manual

Four different configurations are available. More configurations can be saved by pressing Save to File and recalled later
by pressing Load From File.
1. Select the configuration to set up: 1, 2, 3, or 4.
2. Check the box for each parameter desired in the Data to Record section.
3. Configure the harmonic values to be recorded, if desired.
4. Choose an Aggregation Period for the recording, which sets how often the recording updates while it is running.
The Model 8336 loses its scheduled recording if it is powered OFF before the recording begins. If it is powered OFF
during the recording, a partial recording will usually still exist but with the first letter of its name changed to "@". The
start and end times requested for the recording might be adjusted by the Model 8336 to be in even multiples of the
averaging period. For instance, if an integration period of 10 minutes was requested, and the start time was 9:03, the
recording might not actually begin until 9:10.

6.4.6 TRANSIENTS

The Transients tab allows you to set up the criteria for capturing transients.
1. In the Threshold of Voltage Difference section of the dialog box, select from the drop-down menu one of the following
options: 4L Same thresholds for all, 3L+N Same except N has its own threshold, or L1+l2+l3+N Separate thresholds.
2. Based on the preceding selection, fill in appropriate values for L1, L2, L3, and N. (Some of these may be greyed out
and inactive, depending on the selected connection type.)
3. Select Maximum number of transients to find. If previous transients are stored in the memory, the maximum available
will be reduced accordingly. The information is available on the screen.
4. In the Threshold of Current Difference section of the dialog box, select the appropriate option in the drop-down menu.
Available options are the same as those in the Threshold of Voltage Difference drop-down menu.
The configuration settings can be saved to a file by clicking the Save to File button and selecting a file name. A previously
saved configuration can be loaded by clicking the Load From File button. A present configuration in the instrument (if
connected) can be read by clicking Re-Read From Instrument.
