POWER QUALITY ANALYZER PW3198

・ Detect an event when the RMS value of harmonics from which the fundamental is removed at intervals of 200 ms exceeds the set threshold value.・ Display the RMS values of high-order harmonic along with the maximum RMS value during the period of occurrence of the event, as well as the period of time from when the event occurs to when it ends.

・ Harmonic components can be measured in the wide frequency range from 2 kHz to 80 kHz.・ Save event waveforms and high-order harmonic waveforms.

・ For a multi-phase system, the individual phases can be measured independently.
