Difference between the transient and other event waveforms (power quality analyzers)
QWhy are the waveforms recorded by the PQ3198/PW3198 different between transient and other events?
The PQ3198/PW3198 measures normal power quality items and transient overvoltage separately and differently:
* Normal power quality event: 200kS/s, waveform saved for "2 cycles + 200ms + 2 cycies" after thinning to 20kS/s
* Transient overvoltage: 2MS/s, waveform saved for 2ms before and after detection as 2MS/s data through 5kHz LPF to remove the fundamental frequency component.
