Figure 22. Current Harmonics
Presentations and creation of timeplots are similar to voltage cumulative frequency.
Note
The nominal value can be modified at any time for the stored measurement
data files to achieve optimal scaling: Select File>Change current
transformer to enter the required nominal current values and reopen the
measurement data file.
Creation of a Timeplot: It is possible to directly view the timeplot for each measured
variable, i.e., its harmonics 1-40 (function A: 1-50), 5 interharmonics, thd, voltage,
Flicker Pst, unbalance, frequency, and current values. Click the respective bar(s) and then
click the Timeplot icon on the Symbol bar of the cumulative frequency.
