Analyzing Logged Data
Check that the appropriate limit value file is selected. Use menu Software
Settings>General>Select Limit value file for analysis.
"Default GWD60 Hz.gwd" is for applications in 60 Hz systems.
"EN 50160.gwd" is preset for limits defined in EN 50160
"50160_61000-2-2.gwd" has limits for harmonics up to the 50
61000-2-2
Timeplot Display
When you first open a data file to analyze, a Timeplot is displayed. See Figure 16.
Refer to the PQ Log Features Reference section for how to view different parameters and
how to manipulate the x and y-axis ranges. The icons and menus for manipulating the
Timeplot display are explained there.
EN 50160 (for Europe)
This view provides a statistical analysis of the measured parameters. From this
presentation we can see which measured variables exceed the limit values set up in the
limit value file (default: according to EN 50160).
The measured values of each measurement row (voltage variations, interruptions, events,
harmonics and flicker) are classified according to the quantity. In function P there are
bars for thd of voltages, the bars "Flicker" represent long term flicker Plt .
