Power and energy quality analysers

The Qualistar models allow you to view

all the inputs simultaneously.

The measurements are displayed as

waveforms; values or Fresnel diagrams.

Harmonics mode

Global THD and per phase on U, I, V and VA in % and RMS value, phase offset

of harmonics. They offer the expert mode for the Harmonics function.

These two instruments can be used to analyse the inuence of the harmonics on

heating of the neutral or on rotating machines

Power/Energy mode

This mode displays all the values concerning power and energy. The “start” and

“stop” keys can be used to activate and deactivate totalizing of the energies.
