The trend toward energy-saving lighting makes fluorescent and LED lights more and more popular. In comparison to light bulbs, there are ballast units used which are working with switching frequencies up to 150 kHz. The high bandwidth and sampling rate (1 MS/s) of the Dewesoft power analyzer guarantee reliable analysis for every kind of lighting device.
The power quality module automatically calculates parameters like Harmonics, THD, Flicker, etc. The advanced math library allows determining efficiency, energy consumption, and calculation of other parameters. E.g. the current through the fluorescent lamp can be determined out of the secondary and the cathode currents.
